[R] Problems with Cosine Similarity using library(lsa)

[Uwe Ligges]

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.

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).
