Dear,
I would like to deal with microarray data, it can run when i deal with
little data. However, the amount number of SNP data are 45181, amount
numbers of animal are 3081,it can not be allocated 1000Mb memory when
i importing them to R

Procedure sentence show:

m<-matrix(scan("D:/SNPdata.txt"),ncol=nmarkers,byrow=TRUE)

Error show:
Error: cannot allocate vector of size 1000.0 Mb


Is there any way to import these data and calculations, i am very
anxious. Thank you very much.


Best regards.
Chen
