In my previous email, I sent the example: > a <- matrix(as.integer(1),nrow=14100,ncol=14100) # 774m > a[1,1] <- 0 # 3.0g > gc() # 1.5g
This is misleading. The correct version is a <- matrix(as.integer(1),nrow=14100,ncol=14100) # 774m a[1,1] <- as.integer(0) # 1.5g gc() # 774m So, the object duplicates, but nothing more. The main part of my previous email (question concerning a possible bug in the behavior of nrow(a) and ncol(a)) remains open.
