I want to generate a sequence from 1 to x by 1 seq(1,x,by=1)
I want the above to return an empty list if x is zero In other languages I can do 1:x:1 to force the increment by to be a positive 1. This syntax does not work in R. In R 1:x gives me 1 0
when x is zero, this is not what I want. The seq statement above throws an error when x is 0. How can I generate a sequence where if the "to" value is less than the "from" value an empty list is generated with no errors?
