Thanks Uwe, you vere right. Now the library is working but I have next problem
as well.
I have loaded a matrix (named matrix_v3) from a TXT file. This matrix was
previously reached using xtabs function. Now I have used this formula to obtain
cosine similarities from my data matrix (following instructions of lsa package
instructions):
> cosine(matrix_v3, y = NULL)
Finally R returns this message:
Error en cosine(matrix_v3, y = NULL) : argument mismatch. Either one matrix
or two vectors needed as input.
I understand that R don't contemplate matrix_v3 like a real matrix. If this is
like this, how can I do? I have tried "as.matrix" but it does not work. Sorry
if my questions are not very fine, but I am newbie in using R.
Thanks again.
