"R Extension and R packages (sparse Matrix)"

Hi,
i'm currently implementing matrix operations within R. I'm passing large high dimensional matrices to the R script which i want to convert to a sparse matrix within R. Therfor i use the "Matrix" package. Once i try some simple operations with such a matrix as x > 0 or Matrix multiplication i get some eroors. I checked the RapidMiner created object by storing it as a file with the "save" operation in my R script within Rapid Miner. When i import this object to a ragular R environment i can carry out all operations on a sparse matrix based on this object.
Is there any issue with external packages, especiially sparse matrices? Can i do matrix operations in RapidMiner as well?
All the best
