Hi everyone!

I am new to the bioinformatics world and I would much appreciate your help. I am following the TCGA Workflow tutorial and at the Genomic Analysis part, specifically on the CNV analysis I get this error Error: vector memory exhausted (limit reached?), when trying to load the information about the abberant regions into a form of matrix(through the load_cnv function of gaia package). In contrast to the tutorial I am using the whole data set from the TCGA COAD project and not limited samples. 

Any ideas on how I could solve it?

Session info:

I would consider whether adding RAM or virtual memory in the form of swap space might make a difference. I am familiar with the process under Linux and UNIX but not under MacOS.
