I'm getting Error in svd(x, nu = 0L, nv = 0L) : infinite or missing values in 'x' when trying to calculate SVD for a 100x2 matrix in an R script. What's funny is that doing the exact same thing for the exact same matrix in the R prompt works perfectly.

I'm using a subset of the columns, so the actual call I'm making is svd(C[,1:i]) where C is the matrix I'm using and i equals 2 when this crashes.
I'm positive that the matrices in the script and in the prompt are the same (I printed them both to different files and diffed them out to make sure!)
So, what could be the problem here?
EDIT
dput(C[,1:i])
