skip.cond: Skip vector/list elements that satisfy a condition

In 42n4/dmr.util: A package with utility functions used in the book Cichosz, P. (2015): Data Mining Algorithms: Explained Using R

Description

This function skips all vector or list elements that satisfy a given condition. It is used in examples presented in the book Cichosz, P. (2015): Data Mining Algorithms: Explained Using R. See Appendix B or http://www.wiley.com/go/data_mining_algorithms for more details.

Usage

skip.cond(l, cond)

Arguments

l	an input vector or list
cond	a one-argument boolean-valued function

Details

The cond function is applied to all elements of l and those for which it returns TRUE are skipped. In particular, l can be a dataframe (a list of columns) and the function can be then used to skip columns that satisfy a condition.
