I have a data frame (daf1), that holds +80000 records, and 10 variables (i.e. 10 columns and some 80000 rows)
> length(daf1) [1] 10 > length(daf1[,1]) [1] 83805 I would like to sample() e.g. 10000 records from this. I use: > daf2 <- sample(daf1, 1000, replace = FALSE, prob = NULL) Error in `[.data.frame`(x, .Internal(sample(length(x), size, replace, : cannot take a sample larger than the population when 'replace = FALSE' As length(daf1) is 10, it thinks I'm taking 10000 samples from a size 10 population... Arghhh How do I go about sampeling from a data frame? :-( Martin ______________________________________________ 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.
