########### DESCRIPTION: ###########
# Returns an array of randomly generated values from the F distribution.
########## DEPENDENCIES: ###########
#
############ VARIABLES: ############
# - 'dim' is the dimension of the output array.
# - 'df1', 'df2' and 'ncp' are from rf().
# - 'byrow' is TRUE if a matrix is requested (length(dim)==2), and the values should be ordered by rows in the matrix. Useful when different expectations are needed for each column of a matrix.
