what is diffrence between NROW and nrow in r

0 votes
If nrow and ncol are already present in r, why are they still present? Do they differ from one another or are they merely aliases?

Matrix, mx (1:12,3,4)

nrow(mx)
NROW(mx)

ncol(mx) \sNCOL(mx)

5 In R, you may always check the code of a function by entering its name without the quotation marks. By doing this, you can observe how NCOL and ncol differ from one another:

NCOL

function # (x)

If length(d-dim(x)) > 1L, then d[2L] is used. else 1L

#

#

ncol

function # (x)

# dim(x)[2L]

#

#

While NCOL checks to see if the argument only has one dimension, in which case it returns 1, ncol always returns the second dimension of the argument.
