Column and row-wise Any/All | R Documentation |

Column and row-wise Any/All of a matrix.

colAny(x) rowAny(x) colAll(x, parallel = FALSE) rowAll(x, parallel = FALSE)

`x` |
A logical matrix with the data. |

`parallel` |
Do you want the computations to take place in parallel? The default value is FALSE. |

The functions is written in C++ in order to be as fast as possible.

A vector where item "i" is true if found Any/All true in column/row "i". Otherwise false.
