Hello, I've been trying to translate some of my slow R code into C code, and I need the complex math functions to be able to do this. I assumed I could access them with #include <R_ext/Complex...

Hello, I was wondering if anyone has a way to test if a package is currently being installed. My solution was to check if environment variable "R_INSTALL_PKG" was unset, something like: "R CMD INSTALL-ing" <- function () !is.na...

I noticed in the Writing R Extensions manual, it says that within a NAMESPACE file, "Only very simple conditional processing of if statements is implemented.". I tried it out myself by importing a Windows exclusive function: if (.Platform$OS.type...

Hello, I can't provide too much help without knowing which packages `hotspot` and `levelplot` come from. It might be something as simple as `as.data.frame(matrixaaaaaa)` instead of `matrixaaaaaa`. On Wed, Jul 7, 2021 at 10:04 AM...

Hello, I've written two functions to emulate do while/until loops seen in other languages, but I'm having trouble documenting its usage. The function is typically used like: do ({ expr1 expr2 ... }) %while% (cond) so I want to document...

1 and 2 are not valid identifiers in R, so you need to surround them with backticks to make them valid, the same as quoting a string: switch(Stst, `1` = print("NO"), `2` = print("YES")) On Wed., Sep. 7, 2022...

It might not be random, depending upon a seed being used (usually by set.seed or RNGkind). However, it's the best method for generating a random number within a specified range without weights. If you want weights, there are...

Hello, I'm working on a function envvars() which I'd like to get, set, and remove environment variables in a manner similar to options(). At the R level, I have this function: envvars <- function (...) .External2(C_envvars, pairlist(...)) and...

There's no fees for using R in publications, but most people will include citations for the R language and any R packages used. You can use function citation() (it might be called citations(), I'm not entirely sure) to...

Hello, @Martin Maechler: %until% and %while% use R's builtin repeat function. Something like do(expr) %until% (cond) repeat { expr if (cond) break } are identical. After %until% and %while% check the arguments look correct, it makes a call to repeat...
