I handle data a lot with R. In R studio, it's easy to use $ to access some layers of a data frame but it doesn't work yet in vscode.
Thanks for your great work

If you enabled R session watcher, then you should be able to complete the first level of names of any object, just like introduced at my blog post about the session symbol completion.

G' day there

Perhaps, I didn't express it clearly. I wanted to mention the suggestion or autocompletion when working with data. E.g. a data frame usually contains a bunch of columns, it'd be great to have the suggestions/autocompletion of a column to use with just a simple $ sign or something.
Another important thing with data handling is to view list. If a dataset is in a format of a nested list. It'd great to have a way to view the list to see its structure (such as view() in R studio). It's necessary to view when it comes to set some loops for the nested list of data.

Another thing is I can't handle python anymore. I tried to open a python file and execute it but the terminal is set to R automatically then it doesn't realize the python code. Did I miss something

Thanks a bunch for your beautiful work

I wanted to mention the suggestion or autocompletion when working with data. E.g. a data frame usually contains a bunch of columns, it'd be great to have the suggestions/autocompletion of a column to use with just a simple $ sign or something.

The session watcher supports session symbol completion (#165), i.e. $, @ and [ to trigger auto-completion of session symbols of list, data.frame and S4 objects. If you properly enabled this feature, it should work out of the box.

Another important thing with data handling is to view list. If a dataset is in a format of a nested list. It'd great to have a way to view the list to see its structure (such as view() in R studio). It's necessary to view when it comes to set some loops for the nested list of data.

We don't have the RStudio-like viewer of nested list at the moment. The session watcher currently only supports a naive list viewer implemented in #150.

Another thing is I can't handle python anymore. I tried to open a python file and execute it but the terminal is set to R automatically then it doesn't realize the python code. Did I miss something

You need to install Python extension to work with python scripts and optionally Pylance and a better language server for Python. Please visit https://code.visualstudio.com/docs/python/python-tutorial for more details.

In my case, auto-completion does not work for data.frame even though "r.sessionWatcher" is enabled. For example, I typed airquality$ in VSCode editor, but it does not suggest any related columns, such as Ozone, Month, etc.

[renkun-ken]

Currently, the completion provided by session watcher is only capable of providing completions from global environment, i.e. variables created by user in globalenv, rather than symbols defined in packages (in this case, airquality comes from {datasets}).

If we implement #440 and use R's built-in completion in editor, we could provide completions like in RStudio but it will suffer from the same problem using such completion too.

@renkun-ken You know what you guys are doing great I love your work. It greatly helps me to make my code tidy and neat using format document in vscode. Perhaps, we are just too familiar with Rstudio for such a long time then we find the auto completion in data handling and some other features e.g. we can run all the codes inside {} with just ctrl + Enter.
I sometimes need to use Rstudio for quickly testing some chunks of codes and parallelly open my work in vs code
