Re: [R] factor(300000, levels=1:300000) gives NA

You can work around this issue by matching the types of the the 'x' and 'levels' arguments to factor(): > factor(30, as.numeric(29:31)) # both are floating point ('numeric') [1] 3e+05 Levels: 29 3e+05 31 > factor(as.integer(30), 29:31) # both are integer [1

I would say having 30 levels is a bad idea... You should be re-thinking your analysis. If you are still convinced that this is necessary, then do it right: factor(30L, levels=1:30) --- Jeff Newmiller
