Expected or desired behavior:

Were there any error messages in the UI, Output panel, or Developer Tools console?

[jennybc]

Can you show us the content of the "Positron R Extension" output channel? That should be logging the effort to discover your R installations.

[ShiweiLin1991]

sorry, i don't know how to find "Positron R Extension", I am just learn to use R. But, such a bug were not appeared untial the release of the version of 2024.08.0-5

[jennybc]

This part of the wiki explains how to access logs:

@jennybc

I have the same Issue, Positron does not find the R intepreter on both of my work Windows machines. I'll try it at home later where I have admin-rights. I installed the latest User-installation

Quick Feedback to the Wiki article you've posted: coming from R-Studio it is not clear what you mean with

"Run the Output: Show Output Channels command to show a list of output channels. You can then select one to view its output by name, like "Positron R Extension"."

Where exactly should I run this command? I do not have any console yet that could interpret the command and the Terminal pane does not evaluate the command.

[blechturm]

@jennybc found out how to do it. For the other R-Studio users: the command you need is CTRL + SHIFT + P then the so-called "command palette" shows up where you can enter the command "Show Output Channels"

This is the output of the Positron R Extension:

As you can see in the Screenshot below Positron does not find my R-Installation

But R-Studio finds R version 4.3.2

Let me know if you need any other outputs or infos about my machine.

[jennybc]

@blechturm or @ShiweiLin1991 Would you be willing to roll back to a previous version of Positron and post the comparable "good log" for comparison, i.e. where the R installation is discovered?

I have been working in the R discovery area, so my hypothesis is that your R installations were previously being discovered ?through registry keys? and now that is not happening. I'm still not sure why (certainly not the intent), but it's a guess. I also can't reproduce this in either of my Windows VMs, so it's some difference in our setups. I notice that for @blechturm the location of the R installation suggests that you don't have admin privileges.

[jennybc]

People can probably get unstuck by putting the parent folder of your desired R binary on the PATH. However I do hope to get more information from the folks on this thread, because it's clear there's been some sort of recent regression and we should be discovering an R installation. So I'd like to identify and fix that!

But here's how to put R on the PATH. Let's assume that R is installed in C:\notADefaultFolder\R-4.2.3 (substitute whatever is true on your system). The entry we want to add to PATH is C:\notADefaultFolder\R-4.2.3\bin\x64.

Go to About your PC > Advanced system settings (in list on the right) > Environment Variables. Add an entry to Path for the user or the system.

[ShiweiLin1991]

As a beginner, I can't understand your needs well. I provide a picture here, hoping to help improve the bug.

[ShiweiLin1991]

When I start use Positron, such bug never appeared until the latest version released.

[michaelgicheru]

Hello there, currently experiencing the same issue with R discovery on the latest release.

In my case, positron is able to identify the latest version of R on my system when not in a folder. This is the output from the Positron R Extension:

When in the context of an existing folder/directory, it is unable to identify any version of R on my system, even with an R script in the directory. Here is the output:

The R version is not identified:

To work with R, I would need to close all folders -> discover R with no folders open -> create new R project/directory

[jennybc]

With Positron 2024.08.0-5, upon a relaunch, which is occurring in a previously-opened folder, I see this in the Window output channel (and all R discovery / launch happens as usual):

I'm curious if those of you seeing no R launch / discovery could share what you see in this channel. Specifically do you see anything like this? This is where we quickly re-launch the version of R you were last running in this workspace:

2024-08-09 08:51:38.830 [info] Language runtime 912077798d99e95f382c96e6337fbb96 (language: R name: R 4.4.1 version: 4.4.1) automatically starting. Source: Affiliated r runtime for workspace
...
2024-08-09 08:51:38.850 [debug] [Ext host 0] Runtime manager for 'R 4.4.1': true

Also curious if you see this (although I imagine you do):

2024-08-09 08:51:38.971 [debug] [Runtime startup] Phase changed to 'discovering'

The reason that I ask is that the Positron R Extension log makes it look like we aren't even attempting discovery, which is very odd.

And, again, if anyone just needs to get unstuck, either of these should do the trick:

1. Put R on your PATH, as described above. OR ...
2. Use a slightly earlier release of Positron, such as 2024.07.0-125.

But I hope some of you stick with me so we can sort this out. I still can't reproduce it. Positron work and troubleshooting will be a bit slow for the next week or so, due to posit::conf.

[keitheleejr]

@jennybc Here are the logs for R Extension. My personal computer has no issues with the current release, so I'm including that log as well. I've also included the Window output you mentioned in your last comment.

2024.07.0-125 (work)

2024.08.0-5 (work)

2024.08.0-5 (personal)

Window Output 2024.08.0-5 (work)
