Maintenance release to fix CRAN issues for GCC 10 -fno-common flag.
tidy_rules() was removed since the code is now in the tidyrules package.
Changes to better work with tibble inputs.
Maintenance release to fix CRAN issues for C string buffers
Fixed a bug in the code that escapes improper characters.
Converted documentation to roxygen2.
Revised some compiler options to reduce R CMD check warnings.
A bug was fixed, found by Duncan Murdoch.
A bug in predictions when sampling was used was fixed by Laurae (a random data witch/magician) (issue 1)
Memory allocation bugs in the R version of the C code, which lead to segmentation faults, were fixed.
A bug was fixed where the model failed if no predictors were included in the model (thanks to Gabe Gershenfeld for the find).
The Windows build configuration was updated.
Some files were synced with the C50 package.
More efficient code was borrowed from the C50 package to write the data file to a string.
A bug related to column names found by David Clifford was fixed.
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 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.
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).
