I'm using the package RDCOMClient with R version 4.0.2. It was downloaded using:

devtools::install_github("omegahat/RDCOMClient")

I'd like to use the package for reading and writing email. I've started this way:

library(RDCOMClient)
folderName <- "AUX"
OutApp <- COMCreate("Outlook.Application")

However, when I try to use any method from OutApp, R crashes, regardless of whether I'm using console R or RStudio. For example:

outMail = OutApp$CreateItem(0)

outlookNameSpace = OutApp$GetNameSpace("MAPI")

Either of these code chunks cause R to encounter a fatal error and the session to be terminated. No errors/warnings along the way, just an immediate crash. str(OutApp) returns that OutApp is of formal class COMIDispatch [package "RDComClient"] with 1 slot (.. @ ref:). OutApp is of length 1 and mode S4.

Any suggestions?

  • https://github.com/omegahat/RDCOMClient/issues/24#issuecomment-654439280 You can choose which version of R to use by holding `ctrl` when opening R studio. R3.6 works for me – billash Aug 18 '20 at 20:27

    See [RDCOMClient#26](omegahat/RDCOMClient), and a suggested workaround (for R-4) in https://github.com/omegahat/RDCOMClient/issues/24#issuecomment-654439280 (as @BillAsh just suggested). – r2evans Aug 18 '20 at 20:28

A minimal commit was created by a helpful user, due to which the code in OP will work for R > 4.0.

Use the following installation:

library(remotes) 
remotes::install_github("BSchamberger/RDCOMClient", ref = "main")
