similar to: Rtools and things dependent on it

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.

This may be a dumb question and the answer may make me feel dumber. I have had trouble for years with R packages wanting Rtools on my machine and not being able to use it. Many packages are fine as binaries are available. I have loaded Rtools and probably need to change my PATH or something. But I recently suggested to someone that they might want to use the tabyl() function in the janitor

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.

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

Richard, 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) ________________________________________ From: R-help <r-help-bounces at r-project.org> on behalf of Richard O'Keefe <raoknz at gmail.com> Sent: Sunday,

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 +

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

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))

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

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

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

Hi Tim This is brilliant - thank you!! I've had to tweak the basePath line a bit (I am on a Linux machine), but having done that, the code works as intended. This is a truly helpful contribution that gives me ideas about how to work it through for the missing fields, which is one of the major sticking points I kept bumping up against. Thank you so much for this. All the best Andy On

I think that even though some Microsoft employees may have good intentions Microsoft as a company can not be trusted. There will be always a danger that they will try to create their own version of R which works only on Windows and that will become increasingly divergent from "other" R. We witnessed such (cursed in my opinion) attempts with their treatment of Java and Internet Explorer.

I think I tried the commands in the right R

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
