caTools (version 1.12)

Tools: moving window statistics, GIF, Base64, ROC AUC, etc.

Description

Contains several basic utility functions including: moving (rolling, running) window statistic functions, read/write for GIF and ENVI binary files, fast calculation of AUC, LogitBoost classifier, base64 encoder/decoder, round-off error free sum and cumsum, etc.
