R help - Feb 2012 - Problems with Cosine Similarity using library(lsa)

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,

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.
