Error in FUN(newX[, i], ...) : invalid 'type' (character) of argument
HI, Dear R community,
I am try use the above codes to get the row sums, but it gave me
errors.
CAN someone help me with this?
If you look at the results of str(en.id.pr) , I think you will find
that one or more of those columns is of class character.
(There is also a rowSums function, but if you have character variables
It's not likely to be of much additional help.)
