[Rcicr-users] New rcicr version on CRAN now

[Dotsch, R. (Ron)]

Dear rcicr-users,

A new version of rcicr (0.3.4.1) is available on CRAN now. It fixes some minor bugs and more importantly: it adds several features, like a new noise type (Gabor), a setting to change the number of spatial scales of the noise, and a new default scaling method, called independent scaling. It should be completely backwards compatible, so your old scripts will work as they should when you update the package.

Here's the full list of changes since version 0.3.0:

NEW FEATURES:
* Added independent scaling. Works like matched scaling but maintains the zero point. Is the new recommended default for generating a single base image.
* Added Gabor noise option. Generate stimuli with generateStimuli2IFC(..., noise_type='gabor'). Almost all functions have been affected in refactoring.
* Added option to specify number of spatial scales
* Added computeCumulativeCICorrelation. Computes cumulative trial CIs correlations with final/target CI. Use for instance for plotting
* Added label parameter to batchGenerateCI, which adds custom identifiable labels to jpegs
* Added targetpath parameter to CI generation functions, so CIs will not by default be placed in working directory, but in ./cis subdirectory
* Added batchGenerateCI to deal with data from any reverse correlation task that does not use inverse noise. This function can be used for a 1IFC, 2IFC with independently generated stimuli, 3IFC, etc.

CHANGES:
* Changed output of autoscale: scaling factor is no longer part of the list of classification images that is returned
* Changed progressbar to dplyr progress bar, no longer dependent on tcltk (so no more dependency on xquartz on OS X). Also adds time estimation.
* Suppressed warning messages if directory for stimulus or ci output already exists.

FIXES:
* Bugfix: images not saved as jpegs when scaling is set to anything other than autoscale in batchGenerateCI and batchGenerateCI2IFC
* Bugfix: When using pre 0.3.0 Rdata file, the parameter matrix will now be truncated to the appropriate numbers of parameters
* Bugfix: NA's in by parameter of batchGenerateCI2IFC() get ignored instead of making R crash. Thank you Elze Ufkes for reporting this bug!
* Bugfix: target path error message for generateCI2IFC()
* Fixed targetci bug (should be empty list by default instead of boolean) in computeCumulativeCICorrelation
curves of trial-final/target CI correlations to estimate how many trials are necessary in your task
* Bugfix in generateCINoise: added possibility of just one stimulus/response

REFACTORING:
* Renamed generateCI2IFC to generateCI and moved it to rcicr.R as it is a general function, and not just for 2IFC reverse correlation tasks
* Created generateCI2IFC wrapper function (wraps generateCI) for backwards compatibility
* Renamed old generateCI to generateCINoise to differentiate between generateCI and generateCINoise

Best,

Ron
