RDCOMClient installation trouble on R-3.6

Question

I cannot install RDCOMClient, using R-3.6

Some background: RDCOMClient works in my R-3.51 instance, and I need to use 3.6, and I need to use RDCOMClient to interact with my desktop's Outlook. mailR and sendmailR are not currently an option.

Thing's I've tried:

I suspect RDCOMClient doesn't support 3.6, seeing as it's not in the directory here: http://www.omegahat.net/R/bin/windows/contrib/, but I figured I'd try here before I move on.

Is there anything I can do to get it working?

Answer 1

This work for me

library("devtools")
install_github('omegahat/RDCOMClient')

Answer 2

You can try accessing it from omegahet. It works perfectly

url <- "http://www.omegahat.net/R/bin/windows/contrib/3.5.1/RDCOMClient_0.93-0.zip" install.packages(url, repos=NULL, type="binary")

Answer 3

there is a package update at http://www.omegahat.net/R/bin/windows/contrib/4.0.0/ that worked for me (R-4.0.3). Guess it should work for R-3.6 too.

Answer 4

It is not so, that RDCOMClient doesn't support R3.6. It only has not (yet) been compiled with 3.6x and been placed in the subdirectory of the current version in the repository "http://www.omegahat.net/R/bin/windows/contrib/3.6/". However the version 0.93-0 compiled with R 3.5x is fully compatible with R 3.6x, just download it from the 3.5 directory "http://www.omegahat.net/R/bin/windows/contrib/3.5.1/" and install as zip from your local PC.

Or do it directly

url <- "http://www.omegahat.net/R/bin/windows/contrib/3.5.1/RDCOMClient_0.93-0.zip"
install.packages(url, repos=NULL, type="binary")

Answer 5

It seems that RDCOMClient doesn't currently support R3-6. To resolve this issue I have to switch to version R3.51 in Options to run RDCOMClient and send the e-mails.

It's not an ideal solution, but will do until they release an updated version.
