RAVETOOLS_TEMPDIR or option ravetools.tempdir.This version fixes a memory issue reported by CRAN check (gcc-UBSAN).
NA_INTEGER is subtracted by one before being converted to R_xlen_t type. This update fixes this issueRcppParallel and copied part of it into inst/include folder, with TBB removed under the GPL-3 license framework.This is an initial version of ravetools. Although a bare minimal set of signal processing functions are provided, it is sufficient to perform preprocess pipelines on most iEEG signals. Some functions are added from the dipsaus package, with considerable performance improvement. The C++ functions have been tested on all major platforms, with different architectures (ARM, i386, x64).

They tend to be faster than normal base-R implementations, depending on the number of CPU cores used.

They may not be fully stable and should be used with caution. We make no claims about them.
