Hi,

I'm working with a numeric matrix with 55columns and 581012 rows and I'm having problems in allocation of memory using some of the functions in R: for example lda, rda (library MASS), princomp(package mva) and mvnorm.etest (energy package). I've read tips to use less memory in help(read.table) and managed to use some of this functions, but haven't been able to work with mvnorm.etest. 

I would like to know the better way to solve this problem, as well as doing it faster.

Best regards,

Pedro Marques
