Currently I've understood that I've to follow a code sequence like this: alfa <- {a moltiplicator} memory.limit(alfa*round(memory.limit()/1048576.0, 2)) library(foreign) hereis <- read.xport("C:/R/ { my exported file sas }") The dimension of { my exported file sas } is 120 mega Is correct to allocate all the file in memory in a variable ( hereis ) ?
