Column and row-wise range of values of a matrix | R Documentation |

Column and row-wise range of values of a matrix.

colrange(x, cont = TRUE) rowrange(x, cont = TRUE)

`x` |
A numerical matrix with data. |

`cont` |
If the data are continuous, leave this TRUE and it will return the range of values for each variable (column). If the data are integers, categorical, or if you want to find out the number of unique numbers in each column set this to FALSE. |

A vector with the relevant values.
