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.

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.
