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.
We do not know what you object matrix_v3 is, so how could we help?
PLEASE do read the posting guide http://www.R-project.org/posting-guide.html
and provide commented, minimal, self-contained, reproducible code.
Thanks again.

Subject: Re: [R] Problems with Cosine Similarity using library(lsa)
The error message suggests that you do not have Java installed. And
since you said it works in 32-bit: You only have a 32-bit Java but no
64-bit Java installed in your machine.

Hi everybody!
I have intended to use library(lsa) on R 64-bits for Windows but it was not
possible. Every time I try to launch library(lsa) function R give me back next
message:
Loading required package: SnowballError : .onLoad failed in loadNamespace() for 'Snowball',
details: call: NULL error: .onLoad failed in loadNamespace() for 'rJava', details: call:
stop("No CurrentVersion entry in '", key, "'! Try re-installing Java and make sure R
and Java have matching architectures.") error: objeto 'key' no encontradoError: package
‘Snowball’ could not be loaded
Of course, I have loaded all necessary packages, but the only way to
library(lsa) works it is on R 32-bits release. The problem here is that R don't
leave me to load all data from my matrix and tell me that it is not able to
load big vectors (may be due to limitations on memory of 32-bit release).
The issue is that I need to calculate cosine similarities on my matrix data.
Has somebody any suggestion or idea about how to do it (a different library or
a formula to get it)?
Thanks in advance.
Best,
AJ
