R: Function similar to the function...

fast_apply_sd_na_rm_T {imp4p} | R Documentation

## Function similar to the function `apply(X,dim,sd,na.rm=TRUE)`.

### Description

This function is similar to the function `apply(X,dim,sd,na.rm=TRUE)` but written thanks to the Rcpp package and therefore faster than `apply(X,dim,sd,na.rm=TRUE)`.

### Usage

    fast_apply_sd_na_rm_T(X, dim)

### Arguments

`X` | A data matrix containing numeric and missing values.
`dim` | A numeric value: 1 if the standard deviation has to be computed for each row of `X`, or 2 if the standard deviation has to be computed for each column of `X`.

### Value

A numeric vector containing the standard deviation of observed values in either each row or each column of `X`.
