Avi , Your question is not dumb. Let me ask a more fundamental question. What is R tools, what does it do, and how is it used. From time to time, I receive a message when I down load a package saying I need R tools. When I receive the message, I don?t know what I should do, other than down load R tools.

David, I greatly appreciate the explanation you gave regarding R tools providing tools available in Linux distros, but not found in Windows. (I am using a windows system). Does this mean that Linux users don't need to use R tools when they want to compile R code? Additionally, thank you for the information about what I should read. I will look at the material again, and hopefully things the

I have also had difficulty running R in RStudio. Has anyone else had problems? It will be a shame if we need to abandon R Studio. It is a very good IDE.

Hi, If I am not mistaken, all Rtools 4.2 (and 4.3) revisions have the same ARP [1] entries, i.e. all report version 4.2.0.1 (or 4.3.0.1). This makes it difficult to determine the installed version (is it possible to determine the installed revision?) and impossible for tools like winget [2] to update Rtools to the latest revision, AFAICT. Would it be possible to track the version in the

I am new to this thread. At the risk of presenting something that has been shown before, below I demonstrate how a column in a data frame can be dropped using a wild card, i.e. a column whose name starts with "th" using nothing more than base r functions and base R syntax. While additions to R such as tidyverse can be very helpful, many things that they do can be accomplished simply

Dear listers, I have update to rtools43 and, using R 4.2.3 I have been surprised not to be able to compile packages needing compilation when updating. Looks like the path given in gcc? -I"C:/PROGRA~1/R/R-42~1.3/include" -DNDEBUG -DNTIMER -I./SuiteSparse_config -DUSE_FC_LEN_T -I"C:/rtools42/x86_64-w64-mingw32.static.posix/include"???? -O2 -Wall? -std=gnu99 -mfpmath=sse

Again, John, we are comparing different designs in languages that are often decades old and partially retrofitted selectively over the years. Is it poor form to use global variables? Many think so. Discussions have been had on how to use variables hidden in various ways that are not global, such as within a package. But note R still has global assignment operators like <<- and its partner

Hello Avi, while something like d$something <- ... may seem like you're directly modifying the data it does not actually do so. Most R objects try to be immutable, that is, the object may not change after creation. This guarantees that if you have a binding for same object the object won't change sneakily. There is a data structure that is in fact mutable which are environments. For

Richard, I sent my prior email too quickly: A slight addition to your code shows an important aspect of R, local vs. global variables: x <- 137 f <- function () { a <- x x <- 42 b <- x list(a=a, b=b) } f() print(x) When run the program produces the following: > x <- 137 > f <- function () { + a <- x + x <- 42 +

TL:DR there are at least three maybe four ways to address this depending on what you plan to do. I usually adjust PATH to add Rtools using .Rprofile. But if you do that then if you want to use the command line to invoke R then you need to set the PATH separately when you start the shell. For this reason some people like to set it in the User Environment Variables control panel... but some Rtools

Although I owe thanks to Ramus and Ivan, I still do not know how to write and "advanced" function. My most recent try (after looking at the material Ramus and Ivan set) still does not work. I am trying to run the lm function on two different formulae: 1) y~x, 2) y~x+z Any corrections would be appreciated! Thank you, John doit <- function(x){ ds <- deparse(substitute(x))

I wonder if the real confusino is not R's scope rules? (begin .) is not Lisp, it's Scheme (a major Lisp dialect), and in Scheme, (begin (define x ...) (define y ...) ...) declares variables x and y that are local to the (begin ...) form, just like Algol 68. That's weirdness 1. Javascript had a similar weirdness, when the ECMAscript process eventually addressed. But the real

Dear dev team, I was sorry to see the announcement of Duncan about his retirement from maintaining the R Windows build and Rtools. Duncan, thank you incredibly much for your 15 years of devotion and your impressive contribution to the R community as a whole. Thinking about the future, I wondered whether there were plans for the succession of Duncan. Is it the intention to continue providing

Good evening. Testing the most recent version of Rtools, the build stops about when text.c is being compiled in the tools package (just after R.Lapack). The compilation is looking for gcc in C:, even though RTOOLS is set for another drive, and the compilation has successfully run until this point. This did not happen last night with version 1955. I've uninstalled and reinstalled Rtools three
