I am trying to thin some occurrence data in order to reduce sampling bias in my presence-only dataset for use in maxent models as follows:

library(spThin)
thinned_dataset_full.100.1 <- thin(loc.data = AP.bioclim.combined.3, lat.col = "Latitude", long.col = "Longitude", spec.col = "Species", thin.par = 5, reps = 100, locs.thinned.list.return = TRUE, write.files = FALSE, write.log.file = FALSE)

1194 1195 1196 1197 1198 1199 1200 1201 1202 1203 1204 1206 
   2    6    4   11    6   20   17   14    7    6    6    1 
[1] "Maximum number of records after thinning: 1206"
[1] "Number of data.frames with max records: 1"
[1] "No files written for this run."

I have noticed that when I run the code several times on the same dataset the resulting output differs each time e.g.

#Attempt 2

library(spThin)
thinned_dataset_full.100.2 <- thin(loc.data = AP.bioclim.combined.3, lat.col = "Latitude", long.col = "Longitude", spec.col = "Species", thin.par = 5, reps = locs.thinned.list.return = TRUE, write.files = FALSE, write.log.file = FALSE)

#Attempt 3

thinned_dataset_full.100.3 <- thin(loc.data = AP.bioclim.combined.3, lat.col = "Latitude", long.col = "Longitude", spec.col = "Species", thin.par = 5, reps = 100, locs.thinned.list.return = TRUE, write.files = FALSE, write.log.file = FALSE)

Could anyone please explain to me why this is and how I can go about deciding which output I should interpret?
