v0.0-6 - added an mafc link for the cloglog link, which permits fitting Weibull psychometric functions on a log stimulus axis. See example(mafc). v0.0-7 - added mafc.weib link that is just an alias for mafc.cloglog - added mafc.cauchit link v0.0-8 - added additional links that include parameters for both upper and lower asymptotes and a function, psyfun.2asym, that is a wrapper for glm and uses the new links to fit a psychometric function with variable lower and upper asymptotes. v0.0-9 - added standard error estimates based on the Hessian from last iteration of optim to the output of psyfun.2asym (suggested by Ralph Pirow). v0.1-0 - second graphic of mafc example set to aspect = "xy" for better rendition - modified column names of data set ecc2 from nyes, nno to Correct and Incorrect, better reflecting the meaning of these variables. v0.1-1 - fixed an unmatched parenthesis in summary.lambda.Rd - fixed a double dot '..' in the name of an Rd file that did not belong v0.1-2 - fixed some warnings for Rd files v0.1-3 - dprime.SD was failing for small values of H and FA when equal (thanks to Paul Willis) v0.1-4 - the argument name of the mafc links (mafc.logit, mafc.probit, etc.) has been changed from m to .m. This should permit these links to work with the glmer function in the lme4a, the development version of lme4. - dealt with some warnings concerning potential partial argument matching v0.1-5 - added possibility for dprime.SD to give negative values (with a warning) for the IO method (suggested by Sverre Stausland) - increased the range of possible d' values obtainable from dprime.SD to 10 (was 5) for method "diff". v0.1-6 - removed LazyLoad from Description v0.1-7 - substituted binomial()$linkinv and binomial()$mu.eta for uses of .Call in mafc and mafc.logit and logit.2asym link functions. v0.1-7 - eliminated some triple colons from examples v0.2-0 - fixed title case per CRAN standards v0.2-1 - added ... to initial functions of SS.calib and SS.RGBcalib to accomadate passing trace and control arguments for nls as required for R > 4.0.3. v0.2-3 - changed URL's to DOI's for JSS citations v0.3 - documentation fix in dprime.SD - corrected version misalignment in package man page and Description file
