resample the columns of a matrix

1 | ```
sample.cols(x, vec = 1:ncol(x), replace = TRUE, incl.first = TRUE)
``` |

`x` |
matrix |

`vec` |
vector, indicates which columns belong together |

`replace` |
boolean, sampling with or without replacement |

`incl.first` |
boolean, if |

Returns a matrix with the same dimensions as `x`

. The columns are resampled from the original columns. The resampling is done with replacement (`replace = TRUE`

) or without (`replace = FALSE`

). Columns which belong together (indicated by vec) are resampled identically, i.e., all values in rows of these are kept together.

sample.cols(matrix(1:15,nrow = 5),vec = c(1,1,2))
