psyphy 0.3 (2023-08-19)

• documentation fix in dprime.SD
• corrected version misalignment in package man page and Description file

psyphy 0.2-3 (2022-01-03)

• changed URL's to DOI's for JSS citations

psyphy 0.2-1

• 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.

psyphy 0.2-0

• fixed title case per CRAN standards

psyphy 0.1-7 (2012-07-29)

• substituted binomial()$linkinv and binomial()$mu.eta for uses of .Call in mafc and mafc.logit and logit.2asym link functions.
• eliminated some triple colons from examples

psyphy 0.1-6 (2011-10-14)

• removed LazyLoad from Description

psyphy 0.1-5 (2011-06-29)

• 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".

psyphy 0.1-4 (2011-06-24)

• 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

psyphy 0.1-3 (2009-09-28)

• dprime.SD was failing for small values of H and FA when equal (thanks to Paul Willis)

psyphy 0.1-2 (2009-08-21)

• fixed some warnings for Rd files

psyphy 0.1-1 (2009-01-26)

• fixed an unmatched parenthesis in summary.lambda.Rd
• fixed a double dot '..' in the name of an Rd file that did not belong

psyphy 0.1-0 (2009-01-14)

• 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.

psyphy 0.0-9 (2008-10-24)

• added standard error estimates based on the Hessian from last iteration of optim to the output of psyfun.2asym (suggested by Ralph Pirow).

psyphy 0.0-8 (2008-07-15)

• 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.

psyphy 0.0-7 (2008-06-06)

• added mafc.weib link that is just an alias for mafc.cloglog
• added mafc.cauchit link

psyphy 0.0-6 (2008-06-02)

• added an mafc link for the cloglog link, which permits fitting Weibull psychometric functions on a log stimulus axis. See example(mafc).
