Hello, I am trying to generate random samples from the following code
### Setting random seed to always create the same ### Random set of points set.seed(0) absences_15000<-absences[sample(nrow(absences), 15000),] points(absences_15000, cex=0.1) ## Subsample_10000 set.seed(0) absences_10000<-absences_15000[sample(nrow(absences_15000), 10000),] dim(absences_10000) I get the following error: Error in sample.int(length(x), size, replace, prob) : cannot take a sample larger than the population when 'replace = FALSE' Any advice?
