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?
Regards,
Lara
