Why does "summary" show number of NAs as non-integer?
summary() is an S3 generic that for your vector dispatches summary.default(). The output of summary default has class "table" and so calls print.table (print is another S3 generic). Look at the code of print.table() to see how it formats the output. -- Bert Gunter Genentech Non-Clinical Statistics South San Francisco, CA "The business of the statistician is to catalyze the scientific learning process." - George E.

set.seed(19) summary( c(NA, runif(10,1,100), NaN) )
Min. 1st Qu. Median Mean 3rd Qu. Max. NA's 7.771 24.850 43.040 43.940 63.540 83.830 2.000 Why isn't the number of NA's just "2" instead of the "2.000" shown above? efg
