Hi all, Could anyone refer to me to a good source to learn how to program a simple control-flow construct* in R, or provide me with a simple example? Control-flow constructs are programmed as primitives, but I would like to be able to do that (if possible) in pure R. The general context is that those functions are a mystery to me. The motivating example is that I would like to create a function

Thanks a lot Jiefei, I had thought of defining a binary operator (inspired by pipes) or simply using an additional condition in the if() calls [e.g. if(foo & fn(bar)) doSomeThing; with fn(bar) returning a logical], but both are workaround that I do not find as elegant as a proper control-flow construct. Thus two questions remain: - is it possible to create a control-flow construct in pure R?

Dear all, I am struggling with an issue related to static vignettes: they work, but only when present in double in the tarball -- in the folder inst/doc and vignettes; see below for details. Details: I am pre-compiling heavy vignettes thanks to the vignette builder R.rsp. So basically, I have PDF files which I want the package to use as Vignettes. For this, I have the following in my

Dear R community, I am a beginner to R and have a question concerning mget, about I could not find anything in the various documentation. I have a column in a dataframe x for which I want to get values in y: mget(x[,1], env=y, ifnotfound=NA) I receive an error mesage: Error in mget(x[, 1], env = y, ifnotfound = NA) : attempt to use zero-length variable name this is probably due to

Currently, when mget() is used to get the value of a function's argument with no default value and no value in the call it returns the empty name (R_MissingArg). Is that the right thing to do or should it return 'ifnotfound' or give an error? E.g., > a <- (function(x) { y <- "y from function's environment"; mget(c("x","y","z"),

Noted Duncan and TRUE... I cannot do more immediately unfortunately, that is always the issue of asking a last minute panic attack question before teaching a course involving the package... I do have /doc in my .Rbuildignore for reasons I can no longer remember... I will dig and create a MRE/reprex. The students will download heavy packages, but they probably won't notice. *Apologies* In the

Hi Alexandre, I'm not an R expert so this is only my personal thought: I don't think you can achieve what you want exactly. A possible solution would be defining a binary operator %*%, where you can replace the asterisk with any function name you want. The function %*% is special since it has two arguments, left operand and right operand respectively. You then can call the `substitute`

Hi, First a bit of disclaimer... I haven't isolated this problem into an easy to reproduce case, and I won't be surprised if the root cause is a fault in my code's use of name spaces or some such. The error I'm seeing is one in which the desired method is not found. What worries me in terms of my expectations of how to debug the problem is that showMethods and selectMethod both

Dear all, I think that there is a bug in the function simulate.lm() when called upon a glm fitted with gaussian family with a link other than identity. The variance of the simulated response is clearly off and an inspection to the code of simulate.lm reveals that it is because the variance is divided by the model weights (precisely, not the prior ones), which is not documented. Can somebody file

Dear R developers, I did not get any reply concerning my email from last week concerning the bug I found in stats::simulate.lm(). The bug shows up when called upon a GLM with family gaussian(). I am confident it is a genuine bug related to a mix-up between weights and prior weights that only impacts the gaussian family (other families have their own simulate functions defined elsewhere). I

This is hard if not impossible to implement for the general case because the default arguments are evaluated in the environment of the function as it

Hi all, The admin from our setup created a script that should help you reproduce our problem (see below). Of course, it may be that it is not an RPM-related issue, but we hope you will have an idea on how to solve the issue all the same. # 1. Prepare VM and set up Samba - install Fedora 38 Workstation (Fedora-Workstation-Live-x86_64-38-1.6.iso). Username: 'user' - disable SELinux (edit

Thanks again, unfortunately it still fails when mounting the drive on a windows machine (even using nolease) on our end. We will prepare a fully reproducible example using a virtual machine.
