Hi I'm trying to speed my loop up. Any Suggestions?? At the moment it takes a few days to run.
THE CODE --------------------------------------------------------------------------------------------------- for(i in 1:11) { for (j in 3:12) { for (k in 1:273107) { y[k,1] <- x[i,j,k] print(y) Rainfall_dataset <- read.table("1km_grid_nzmg.csv", header=TRUE, sep=",", na.strings="NA", dec=".", strip.white=TRUE) t <- Rainfall_dataset print(t) p<-cbind(t,y) #y<-cbind(t,y) #print(y) } # This where you write out array y to a csv file # Save output as a csv file site <- paste("site",i,"-",j) csvfile <- paste(site,sep=".","csv"); print(csvfile) path<- paste("c:/Data/",csvfile) print(path) write.csv(p,file=path, row.names = TRUE) } } -- View this message in context: http://r.789695.n4.nabble.com/Speeding-nested-loops-up-tp3751485p3751485.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
