[datatable-help] fread always read the last line when skipping

[Emilio Torres Manzanera]

Dear Sir,
If I use the skip option with a number greater than or equal to the number of rows of the file, it always reads the last record. It would be nice to get a NULL record in such situation.
Do you know to get this result? Thank you
Best regards
Emilio
library(data.table)
write.table(iris,"iris.csv",row.names=FALSE, col.names=FALSE)
a <- fread("iris.csv")
dim(a) # 150 records
b <- fread("iris.csv",skip=250,nrows=10) ## We skip a lot of records
b # it always return the record #150
