Re: [R] Question about Rfast colMins and colMaxs

What puzzles me is why you are not just using lapply(some.data.frame, min) lapply(some.data.frame, max) or as.vector(lapply(...)) Why go to another package for this? Is it the indices you want? col.min.indices <- function (some.data.frame) { v <- sapply(some.data.frame, function (column)

Those are both helpful comments. Would it not be useful to say something along these lines in ?class. ? The key point I missed is that there often(but not always) must be an *explicit* class **attribute** for method dispatch; and class() does not indicate whether its value is explicit or not (just

Re: [R] A technical question on methods for "+"

The reason for this behaviour is that finding methods is a lot slower than just evaluating the built-in function. So R takes the time to determine if there's an attribute named "class" attached, but doesn't go searching further if there isn't one. Duncan Murdoch On 02/12/2021 3:10 p.m., Andr

class() does not always return the class attribute, try something more like attr(, "class"), you'll see what I mean On Thu, Dec 2, 2021, 15:23 Bert Gunter wrote: > "This is because + dispatches on the class attribute, which a string > like "test" has set to NULL" > Not true. > > > class('test')

Re: [R] A technical question on methods for "+"

This is because + dispatches on the class attribute, which a string like "test" has set to NULL, so it doesn't dispatch. You can add the class yourself like structure("test", class = "character") and that should work. I'm not sure where it's explained, but most primitive functions dispatch on the

I think the fact that character is a built-in type rather than an S3 class has something to do with it. On December 2, 2021 11:31:47 AM PST, Bert Gunter wrote: >... and probably a dumb one and almost certainly not of interest to >most R users. But anyway... > >?"+" says: >"The unary and binary a
