Problem in running codes in R

[arnabkdey]

Hi,

I am having trouble executing simple functions in R. For example:

I first create a simple dataframe as such:

df <- data.frame( a = c(1:10), b = rep(c(0:1), 5), c = c(11:20) )

When I run this, the plug-in shows a pop-up saying Done! However, when I try to use the dataframe it throws errors:

head(df)

gives the following error:

function (x, df1, df2, ncp, log = FALSE) { if (missing(ncp)) .Call(C_df, x, df1, df2, log) else .Call(C_dnf, x, df1, df2, ncp, log) }

and

mean(df$a)

gives the following error:

Error in df$a : object of type 'closure' is not subsettable Calls: mean Execution halted

I would really appreciate any help in resolving this.

Thank you.

Hi! I think I may know the problem: are the first and second statements in different code blocks?

If so: using variables from one code block in another block is a feature of Notebook Mode, which is only available for Python and Javascript right now. I can work on R-lang Notebook Mode, but I'm in midterms season at the moment, so it might be a bit until it lands & gets published.

If not: please provide the following information and I can help you with debugging the issue!

• OS & version
• Rscript version
• Plugin version
• A screenshot of your plugin settings, with R visible
• How long have you had this issue?

You are right - using the variables in the same code block solves the problem.

It would be great if the Notebook mode is available for R as well.

Thanks so much and good luck with mid-terms!!

Great! I'm glad that it was fixed :)

Sure! I'm not sure when it'll be finished-- to be honest, I don't have a lot of experience with R-- but I will work on it when I can, and merge my work after #140 gets merged (that PR makes it much easier for us to add Notebook Mode to new languages)

Thank you!!!!

Heyo! I wanted to let you know that I finished & submitted a PR. The feature should be available in master pretty soon (assuming I haven't made any glaring errors with the implementation!)

That is just fantastic. This is going to be so great for my workflow. Thank you so much for your consideration and your work on this :)
