...e large amounts of data the systems configuration are Speed: 3.4 GHz, memory 4GByte. Is there a way to change the settings or processor under R? I want to run the function Random Forest on my large data set it should be able to cope with that amount. Perhaps someone has tried this before in R or is Fortram a better choice? I added my R script down below. Best regards, Iris Kolder SNP <- read.table("file.txt", header=FALSE, sep="") # read in data file SNP[SNP==9]<-NA # change missing values from a 9 to a NA SNP$total.NAs = rowSums(is...

Do we need to have a special compile library path set in the Makefile to direct CRAN to the R distributed fortram libraries?

Example Code on OSX/Mac: install.packages("SWATmodel",repos="http://cran.r-project.org") library("SWATmodel") testSWAT2005() d...
