I was trying to develop a program in R to estimate a Spearman correlation with Rcpp. I did it, but it only works with matrix with less of a range between 45 00 - 50 000 vectors. I don't know why, but it only works with that dimension. I suppose there's limit with that type of information, maybe if I work it like a data.frame? I would really appreciate if someone gives me insight.
To repeat more succintly:
You can have more than 2^31-1 elements in a vector.
Matrices are vectors with
You can have more than 2^31-1 elements in a matrix (ie
Your row and column index are still limited to 2^31.
Example of a big vector:
R> n <- .Machine$integer.max + 100 R> tmpVec <- 1:n R> length(tmpVec)  2147483747 R> newVec <- sqrt(tmpVec) R>
