QUESTION
I am trying to use Visual Studio for R for the first time, and am having a hard time starting.
I have installed VSCode as a binary on my Windows machine (needed because of corporate machine).
My R executables are in my documents folder (also because I'm on a corporate machine).
I have downloaded R and R Debugger extensions in VSCode. *I could not find R LSP Client, even though tutorials from 2020 showed that it was necessary.
I have installed languageserver in my R client, and have also done pip install radian.
My settings.json looks like this:
...ANSWER
Answered 2022-Feb-18 at 21:36Step 1: Ensure R is setup right:
In your JSON settings, change r.rpath.windows and --r-binary from
"C:\\Users\\XXXXX\\Documents\\R\\R-4.0.3\\bin\\x64\\R.exe"
to
"C:\\Users\\XXXXX\\Documents\\R\\R-4.0.3\\bin\\R.exe"
(That is, drop the \\x64--and don't worry, VSCode should still open 64-bit R even with these changes).
Step 2: Fix the issue of running an R Script from the Editor:
In your JSON settings, add the following line:

I try using a very light-weighted editor BowPad to edit and run codes.
Take running R as an example, which has been added to Windows PATH Environment Variable D:\R\R-3.6.2\bin\x64
I try to take some following steps:
- I built a
test.rwriting some testing line codes as1+2; plot(1:10) - Menu --> Run --> Configure custom commands
- Command Name:
run R - Command Line:
D:\R\R-3.6.2\bin\R.exe $(SEL_TEXT)$(LINE) The line where the cursor is$(POS) the position where the cursor is$(TAB_PATH) the path to the file of the active tab$(TAB_NAME) the file name without extension of the current tab$(TAB_EXT) the file extension of the current tab$(TAB_DIR) the directory of the file of the active tab$(SEL_TEXT) the selected text or the word at the cursor position$(SEL_TEXT_ESCAPED) like $(SEL_TEXT) but escaped, useful for urls
- Command Name:
When I press to choose run R to run the code, something wrong happens!
- It will open a
Rterm(64-bit)window each time when Irun R! - it shows
RGUMENT '1+2' __ignored__orARGUMENT 'plot(1:10)' __ignored__
Did I missing something ? BTW, can we set some shortcuts keys for running Python, R, Octave or Julia?
Also, when I reach the homepage of BowPad for more information, little usage of this software can be found!
...ANSWER
Answered 2022-Jan-15 at 17:56R.exe refers to Rterm. You can use Rgui.exe instead but that won't automatically process arguments. I think what you likely want is to send the selected text to a running R session rather than starting up a new R session each time.
To do that
download this file and optionally place it on your path https://raw.githubusercontent.com/ggrothendieck/batchfiles/master/clip2r.js
in the Bowpad Run | Configure window configure a Run R command as the following (or if clip2r.js is not on your path use the entire pathname). It should be just like this with no arguments.
QUESTION
I'm new to VS Code and am trying to use R there. I think I have it set-up correctly with all required sub-programs installed. When attempting to print "Hello World", the output tab produces messages that makes me think VS Code is recognizing the R code. Also, I can hover over my R code in VS Code and the hints pop up explaining the R functions; so I did something right I think.
I noticed that the bottom right of the VS Code screen says "R: (not attached)"
When I click on that and try to attach it, I get this:

Answered 2021-Nov-23 at 20:52Based on what is in your JSON settings, it should work if you remove the \\x64 portion of your r.path.windows and r.term.windows paths:
QUESTION
I'm using VSCode to write R(version 4.1.0) on Windows 10, also I have installed radian. It seems that each setting is on the right way, but I can only excute Rscript. The default terminal is also on cmd but not on radian.
...ANSWER
Answered 2021-Sep-23 at 08:32VSCode is a language agnostic IDE, so it won't set R or Radian as default unless you set to (actually, you shouldn't do that. let cmd as default).
To open an R terminal, open the command pallet with CTRL+SHIFT+P or F1 and type "R: create terminal".
If yet you want to use radian as default (which, again, you shouldn't), add a Radian profile:
QUESTION
I am trying to write a Julia function (weighted_sum in this example) and use it in R.
The function works well in Julia (first code block below), but fails to work with NAs when called from R using the JuliaCall package (second block of code below).
Is there a way around this problem? E.g. Could I modify the Array type somehow in the R version of the function (within JuliaCall::julia_eval()) so that it accepts R's NAs?
Julia code:
...ANSWER
Answered 2021-Sep-05 at 20:25According to this, the missing in julia is kind of a generalization of the missing values in other languages. It is not clear why the NA from R is having a problem. Tried changing to NaN as input and it works by using isnan
QUESTION
I just noticed that read_csv() somehow uses random numbers which is unexpected (at least to me). The corresponding base R function read.csv() does not do that. So, what does read_csv() use the random numbers for? I looked into the documentation but could not find a clear answer to that. Are the random numbers related to the guess_max argument?
ANSWER
Answered 2021-Jun-10 at 19:21tl;dr somewhere deep in the guts of the cli package (called to generate the pretty-printed output about column types), the code is generating a random string to use as a label.
A major clue is that

QUESTION
The example below is a simple one which tries to assert the column y is always positive (y>0). How can I extract the errored data (row 3 with the negative value,into a dataframe maybe, or any convenient object) while allowing the workflow to continue with "cleaned" data?
...ANSWER
Answered 2021-Apr-12 at 09:23This is tricky, and the answer below doesn't solve this 100%. Now there are a number of different ways assertr lets you handle errors/stops, just see ?error_stop (which is the default).
You need to not only filter out rows that fail, but also collect them (all) for later inspection.
Below I wrote my own error handler. It fetches those rows that fail, filter them away, and stores them in the global environment under the varibale my.failed.rows.

ANSWER
Answered 2020-Oct-23 at 18:34The problem is your have multiple values for n_users for each group. The latest version of dplyr allow you to return more than one row per group if your summary function returns multiple values.
If you want to assume all the values for n_users will be the same per group, then you can do
QUESTION
This may be a usage misunderstanding, but I expect the following toy example to work. I want to have a lagged predictor in my recipe, but once I include it in the recipe, and try to predict on the same data using a workflow with the recipe, it doesn't recognize the column foo and cannot compute its lag.
Now, I can get this to work if I:
- Pull the fit out of the workflow that has been fit.
- Independently prep and bake the data I want to fit.
Which I code after the failed workflow fit, and it succeeds. According to the documentation, I should be able to put a workflow fit in the predict slot: https://www.tidymodels.org/start/recipes/#predict-workflow
I am probably fundamentally misunderstanding how workflow is supposed to operate. I have what I consider a workaround, but I do not understand why the failed statement isn't working in the way the workaround is. I expected the failed workflow construct to work under the covers like the workaround I have.
In short, if work_df is a dataframe, the_rec is a recipe based off work_df, rf_mod is a model, and you create the workflow rf_workflow, then should I expect the predict() function to work identically in the two predict() calls below?
ANSWER
Answered 2020-Oct-19 at 19:49The reason you are experiencing an error is that you have created a predictor variable from the outcome. When it comes time to predict on new data, the outcome is not available; we are predicting the outcome for new data, not assuming that it is there already.
This is a fairly strong assumption of the tidymodels framework, for either modeling or preprocessing, to protect against information leakage. You can read about this a bit more here.
It's possible you already know about these resources, but if you are working with time series models, I'd suggest checking out these resources:
