Computes the standard deviation of the values of x.
Usage
std(x, flag = 0)
Arguments
x
numeric vector or matrix
flag
integer logical. If 0, selects unbiased algorithm.
If 1, selects biased algorithm (currently unsupported).
Value
Return value depends on argument x. If vector, returns
the standard deviation. If matrix, returns vector containing
the standard deviation of each column.
