Seems that supertype(Num) yields Real and hence PyCall tries to convert it into Float64 before showing in Python.

A simple workaround would be to provide your own wrapper:

RStudio crashing when trying to use Python or Julia

Asked 2021-Nov-10 at 13:57

RStudio crashes for me whenever I try to use a different language engine like Python (anaconda or Python) or Julia. I can run library(reticulate) and library(JuliaCall) but when I actually start typing in a code chunk and try to execute python or julia code, the session crashes.

For Julia, I receive a first message that says,

"Error Autosaving File. RStudio was unable to autosave this file. You may need to restart RStudio."

Then I get the

"R Session Aborted"

message with the bomb and 'Start New Session' button. No code or other messaging is provided in RStudio.

I've uninstalled and reinstalled R, Python and Julia multiple times with no resolution.

When I try to use pure R and Julia, for example, below is the output (no messages for Python unfortunately). I am more interested in getting Python up and running in RStudio.

Answered 2021-Nov-10 at 13:57

I had the same problem (using library(reticulate)), with the same versions of R, RStudio and MacOS as you reported. My problem was solved by installing the previous version of RStudio, i.e., Version 1.4.1717.

Running my code in an R console or the IDE bundled with R also worked.

Passing NAs from R to a Julia function using JuliaCall

Asked 2021-Sep-13 at 20:09

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:

Answered 2021-Sep-05 at 20:25

According 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

Rmarkdown is only aware of any code that is run in the immediate session, to avoid creating documents that will be impossible to compile by itself.

As such you'll have to add the code to the initial code chunk
