For loop with NULL fails

[RamiKrispin]

It seems like when assigning a value with NULL within a for loop and executing it from a script file (i.e., command + enter), it skips the code below and breaks the loop. For example:

for (i in 1:nrow(iris)) {
    x <- NULL
    print(i)
}

results on the radian terminal:

r$> for (i in 1:nrow(iris)) {
            x <- NULL
    }

r$>     x <- substr(iris$Species[i], start = 1, stop = 2)

r$> }
Error: unexpected '}' in "}"

r$>

Code will work if running directly on the terminal.

I am running the code with VScode inside a container:

Did you turn on the bracketed paste mode in VSCode-R?

[RamiKrispin]

That worked!

I am running R inside a containerized environment and I have the r.bracketedPaste argument set to true on the .vscode\settings.json file:

{
    "r.alwaysUseActiveTerminal": true,
    "r.bracketedPaste": true,
    "r.sessionWatcher": true,
    "r.plot.useHttpgd": true,
    "grammarly.files.include": ["**/README.md", "**/readme.md", "**/*.txt"]
}

I always thought that at the project level, the settings.json file is the source of truth.

Thanks for the prompt response!

Actually I have no idea what you have said 😜. Anyway, glad that you have figured it out.

When working in a containerized environment with the Dev Container extension, it should enable you to define the VScode setting for the container regardless of your local VScode settings with the settings.json file. The issue with the brackets should be taken care by the r.bracketedPaste": true argument but it seems that it doesn't...
