Cubist 0.0.12 (2012-02-29)

• A bug was fixed that occurred when splits were determined in models with a categorical variable involving more than two categories (eg. "if X4 in {a, b}")

• Also, a bug was found in the variable importances calculations when a variable was used only in the conditions and not the model.

• The 'doc' directory was moved into the "vignettes" directory

Cubist 0.0.11 (2012-02-15)

• cubist uses a string buffer to capture the output files that would normally get saved to external files. The package was failing R CMD check only on windows because the output files were getting garbled. s*printf functions work differently on Windows. On Linux, they return the size that is needed to correctly print the string. On Windows, if there isn't enough space, they return -1.

• Also, work-arounds were added to the C sources because of R CMD check issues. printf(), assert() and exist() statements were removed or redefined.

• A bug was fixed for the coef method.

Cubist 0.0.6 (2011-04-30)

• The GPL version was revised to be version 3 (thanks to Ross Quinlan for the note).

• The variable usage statistics were saved to a data frame in called object$usage. The package vignette and help files were updated accordingly.

• When using cubist, if x was a vector or a single variable, an error occurred. This was fixed.

• The vignette was also expanded to show how caret can be used to tune the model and a technical error was corrected about the boosting algorithm (thanks again to Ross Quinlan).
