Hi Ramon, Thanks for your info. I will look at the paper you mentioned below and get back to you if I need more details about your package.

Hi Yu, You might also have a look at Dchip, CNAG and GEMCA. Theye are no R packages but should be able to calculate the CNs for you up to the 500k chips. However I would like to join Yu here in one point: Is there already any package which can handle the new SNP6.0 chips? As far as I know not yet, or is there one?

The paper by Yu et al., 2007, BMC Bioinformatics,8: 145+ (http://www.biomedcentral.com/1471-2105/8/145/abstract), for example, compares their performance.
