Hi the following example I think demonstrates the inconsistency > f<-function(x) x > length(f) [1] 1 > is.na(f) [1] FALSE Warning message: In is.na(f) : is.na() applied to non-(list or vector) of type 'closure'
The documentation states: Arguments x an R object to be tested. value a suitable index vector for use with x. And nowhere in the details was it implied (to me anyway) that x could not be a function or anything else in R for that matter. Did I miss something?
