...xi = REAL(x)[i]; yj = REAL(y)[j]; if (!ISNAN(xi) || !ISNAN(yj)) return xi == yj; return R_IsNA(xi) == R_IsNA(yj); } The logic of the cequal() function (in the same file) could also be cleaned up in a similar way, probably for an even greater speedup.

...s in real-life cases, I think this enhancement should certainly be considered. Also, in a worst case scenario of a long vector with only one duplicated value, the suggested change does not slow down the calculation. Here's a proof of concept: as.Date.character2 <- function(x, ...) { if (anyDuplicated(x)) { ux <- unique(x) idx <- match(x, ux) y <- as.Date.character(ux, ...) return(y[idx]) } as.Date.character(x, ...) } ## Example1: Construct a 1-million length character vector of 1000 unique dates ## By considering only unique values, speed...

...and subtraction operators map them to integer results (giving NA's if the result cannot fit into 32 bits). Perhaps it was a mistake to include the integer type, but at the time S was developed it made sense. As for table(table(x)) being an unnatural construct, I use it all the time instead of anyDuplicated to see the pattern of duplications.

Hello. It would be great if the grep function in R had the option to use the -m parameter as the linux command does. That would allow to stop a grep search as soon as something is found. It would make many operations much faster. [[alternative HTML version deleted]]

length(unique(c(1,2,2)))==length(c(1,2,2)) I use the above test to test if all the elements in a vector are unique. But I'm wondering if there is a convenient function to do so in R library.

Hi all, So I've started working on this and I ran into something that I didn't know, namely that for x a multi-dimensional (2+) array, head(x) and tail(x) ignore dimension completely, treat x as an atomic vector, and return an (unclassed) atomic vector: > x = array(100, c(4, 5, 5)) > dim(x) [1] 4 5 5 > head(x, 1) [1] 100 > class(head(x)) [1] "numeric" (For a

...mething we should consider changing for R 4.0.0 -- to have it TRUE also for 2d-arrays aka matrix objects ??) The consequence of that is that currently, "often" foo.matrix is just a copy of foo.array in the case the latter exists: "base" examples: foo in {unique, duplicated, anyDuplicated}. So I propose you change current head.matrix and tail.matrix to head.array and tail.array (and then have head.matrix <- head.array etc, at least if the above quirk must remain, or remains (which I currently guess to be the case)). >> x = array(100, c(4, 5, 5)) &gt...

So I have a function that does lapply's for me based on dimension. Currently only works for length(pivotColumns)=2 because I haven't fixed the rbinds. I have two versions. One runs WAYYY faster than the other. And I'm not sure why.
