A few functions I packaged. This is the public version of a private library.
dsLibs() - common Data Science libraries
dynamic_name() - quickly generate code for automatically updating output file names by date.
factorFix() - ensure matching features b/t train and test. Also numeric mean imputation for numeric columns.
rm_cons() - drop constant features
rm_ident() - drop identical features
setdiff2() - bidirectional setdiff
and so on.
