You have use a zero index. This is not allowed in R (normally).
Also your code, even if corrected, would do nothing so I suspect your problems
do not stop there.
Did you really mean "for(i in v) .... if(v[i] ... "? Very subtle if
you did.

Subject: [R] any suggestions on this error?
Error in matrix(unlist(value, recursive = FALSE, use.names = FALSE), nrow nr, :
invalid 'ncol' value (too large or NA)
the statement was:
for (i in v) {for (j in m[0,]){if(v[i]==m[0,j]){M[,-j]}}}
where 'v' is a vector, and 'm' and 'M' are both
matrices.
