Update configure file to extend support for GCC
Correct warnings in NEWS.Rd (strong)
Correct typo in funique.Rd thanks to @davidbudzynski
Function pprod now returns double output even if inputs are integer - in line with base::prod - to avoid integer overflows.
Update configure file
Function pcountNA is equivalent to pcount(..., value = NA).
Function pcountNA and pcount(..., value = NA) allow NA counting with mixed data type (including data.frame). pcountNA also supports list-vectors as inputs and counts empty or NULL elements as NA.
Functions panyv, panyNA, pallv and pallNA are added as efficient wrappers around pcount and pcountNA. They are parallel equivalents of scalar functions base::anyNA and anyv, allv and allNA in the 'collapse' R package.
Functions pfirst and plast are added to efficiently obtain the row-wise first and last non-missing value or non-empty element of lists. They are parallel equivalents to the (column-wise) ffirst and flast functions in the 'collapse' R package. Implemented by @SebKrantz.
Functions psum/pprod/pmean also support logical vectors as input. Implemented by @SebKrantz.
Function charToFact was not returning proper results. Thanks to @alex-raw for raising an issue.
Function pprod now returns double output even if inputs are integer - in line with base::prod - to avoid integer overflows.
C compiler warnings on CRAN R-devel caused by compilation with -Wstrict-prototypes are now fixed. Declaration of functions without prototypes is depreciated in all versions of C. Thanks to Sebastian Krantz for the PR.
Function pcount now supports data.frame.
Function pcount now works with specific NA values, i.e. NA_real_, NA_character_ etc...
Function psum, pmean, pprod, pany and pall now support lists. Thanks to Sebastian Krantz for the request and code suggestion.
Function topn should now work for ALTREP object. Thanks to @ben-schwen for raising an issue.
Re-organise header to prevent compilation errors with new version of Clang due to conflicts between R C headers and OpenMP.
Function funique now preserves the attributes if the input is a
data.table, tibble or similar objects. Thanks to Sebastian Krantz for the request.
Function topn now defaults to base R order for large value of n.
Please see updated documentation for more information ?kit::topn.
Function charToFact gains a new argument addNA=TRUE to be used
to include (or not) NA in levels of the output.
Function shareData, getData and clearData implemented
to share data objects between R sessions. These functions are experimental and might change in the future.
Feedback is welcome. Please see ?kit::shareData for more information.
Few calloc functions at C level have been replaced by R C API function
Calloc to avoid valgrind errors/warnings in Travis CI.
Errors reported by rchk on CRAN have been fixed.
Function charToFact gains a new argument decreasing=FALSE to be used
to order levels of the output in decreasing or increasing order.
Function topn gains a new argument index=TRUE to be used return
index (TRUE) or values (FALSE) of input vector.
Some tests of memory access errors using valgrind and AddressSanitizer were reported by CRAN.
An attempt to fix these errors has been submitted as part of this package version. It also seems that
these same errors were causing some tests to fail for funique and psort on some platforms.
Functions pmean, pprod and psum will result
in error if used with factors. Documentation has been updated.
Function funique and fduplicated gain an additional argument
fromLast=FALSE to indicate whether the search should start from the end or beginning
PR#11.
Functions pall, pany, pmean,
pprod and psum accept data.frame as input
PR#15. Please see documentation for more
information.
Function charToFact is equivalent to to base R as.factor but is much
quicker and only converts character vector to factor. Note that it is parallelised. For more
details and benchmark please see ?kit::charToFact.
Function psort is experimental and equivalent to to base R sort
but is only for character vector. It can sort by "C locale" or by "R session locale".
For more details and benchmark please see ?kit::psort.
A few OpenMP directives were missing for functions vswitch and
nswitch for character vectors. These have been added in
PR#12.
Function funique was not preserving attributes for character, logical and
complex vectors/data.frames. Thanks to Sebastian Krantz (@SebKrantz) for bringing that to my
attention. This has been fixed in PR#13.
Functions funique and uniqLen should now be faster for
factor and logical vectors PR#14.
Function uniqLen(x) is equivalent to base R length(unique(x)) and
uniqueN in package data.table. Function uniqLen, implemented in C, supports
vectors, data.frame and matrix. It should be faster than these functions. For more
details and benchmark please see ?kit::uniqLen.
Function vswitch now supports mixed encoding and gains an additional argument
checkEnc=TRUE. Thanks to Xianying Tan (@shrektan) for the request and review
PR#7.
Function nswitch is a nested version of function vswitch
and also supports mixed encoding. Please see please see ?kit::nswitch for further details.
Thanks to Xianying Tan (@shrektan) for the request and review PR#10.
Small algorithmic improvement for functions fduplicated, funique
and countOccur for vectors, data.frame and matrix.
A tests folder has been added to the source package to track coverage and bugs.
Function nif has been split into two distinctive functions at C level,
one has its arguments evaluated in a lazy way and is for R users and the other one (nifInternalR)
is not lazy and is intended for usage at C level.
Function countOccur(x), implemented in C, is comparable to base
R function table. It returns a data.frame and is between 3 to 50 times faster.
For more details, please see ?kit::countOccur.
Functions funique and fduplicated now support matrices.
Additionally, these two functions should also have better performance compare to previous release.
Functions topn has an additional argument hasna=TRUE to indicates whether
data contains NA value or not. If the data does not contain NA values, the function
should be faster.
A few C functions have been added to subset data.frame and matrix as well as
do other operations. These functions are not exported or visible to the user but might become
available and callable at C level in the future.
Function fpos was not properly handling NaN and NA for complex
and double. This should now be fixed. The function has also been changed in case the 'needle' and
'haysatck' are vectors so that a vector is returned.
Functions funique and fduplicated were not properly handling
data containing POSIX data. This has now been fixed.
Functions fduplicated(x) and funique(x), implemented in C,
are comparable to base R functions duplicated and unique. For more details,
please see ?kit::funique.
Functions psum and pprod have now better performance for
type double and complex.
Function count(x, y) now checks that x and y have the same class and
levels. So does pcount.
Function pmean was not callable at C level because of a typo. This is now fixed.
Function count(x, value), implemented in C, to simply count the number of times
an element value occurs in a vector or in a list x. For more details, please see
?kit::count.
Function pmean(..., na.rm=FALSE), pall(..., na.rm=FALSE),
pany(..., na.rm=FALSE) and pcount(..., value), implemented in C,
are similar to already available function psum and pprod. These
functions respectively apply base R functions mean, all and any element-wise.
For more details, benchmarks and help, please see ?kit::pmean.
Fix Solaris Unicode warnings for NEWS file. Benchmarks have been moved from the NEWS file to each function Rd file.
Fix some NA edge cases for pprod and psum so these
functions behave more like base R function prod and sum.
Fix installation errors for version of R (<3.5.0).
Function fpos(needle, haystack, all=TRUE, overlap=TRUE), implemented in C, is
inspired by base function which when used in the following form
which(x == y, arr.ind =TRUE). Function fpos returns the index(es) or position(s)
of a matrix/vector within a larger matrix/vector. Please see ?kit::fpos for more
details.
Function iif(test, yes, no, na=NULL, tprom=FALSE, nThread=getOption("kit.nThread")),
originally contributed as fifelse in package data.table, was moved to package kit
to be developed independently. Unlike the current version of fifelse, iif allows
type promotion like base function ifelse. For further details about the differences
with fifelse, as well as hutils::if_else and dplyr::if_else, please see
?kit::iif.
Function nif(..., default=NULL), implemented in C, is inspired by
SQL CASE WHEN. It is comparable to dplyr function case_when however it
evaluates it arguments in a lazy way (i.e only when needed). Function nif was
originally contributed as function fcase in the data.table package but then moved
to package kit so its development may resume independently. Please see ?kit::nif for
more details.
Function pprod(..., na.rm=FALSE) and psum(..., na.rm=FALSE),
implemented in C, are inspired by base function pmin and pmax. These new
functions work only for integer, double and complex types and do not recycle vectors. Please
see ?kit::psum for more details.
Function setlevels(x, old, new, skip_absent=FALSE), implemented in C,
may be used to set levels of a factor object. Please see ?kit::setlevels for more details.
Function topn(vec, n=6L, decreasing=TRUE), implemented in C, returns the top
largest or smallest n values for a given numeric vector vec. It is inspired by
dplyr::top_n and equivalent to base functions order and sort in specific cases as shown
in the documentation. Please see ?kit::topn for more details.
Function vswitch(x, values, outputs, default=NULL, nThread=getOption("kit.nThread"))
, implemented in C, is a vectorised version of base R function switch. This
function can also be seen as a particular case of function nif. Please see
?kit::switch for more details.
