[R] Requesting for help on the problem of "subscript out of bounds"

[Jim Lemon]

Hi Subhamitra,
Where I think the error arises is in the line:

 N<-nrow(mat)

Since we don't know what "mat" is, we don't know what nrow(mat) will
return. If "mat" is not a matrix or data frame, it is likely to be
NULL. Try this:

print(N)

after defining it and see what it is.
