[R] IBM Power vs Markdown

[Marc Schwartz]

Hi,

As I was doing some searching, it would appear that you also posted to the package's GitHub repo and obtained a solution there:

  https://github.com/rstudio/markdown/issues/88

For specific packages, in situations like this, contacting the package maintainer as you did, is a good first step.

For future reference, since you are running on RH, there is the R-SIG-Fedora list, which covers issues associated with running R on RH and Fedora based distros:

Regards,

Marc Schwartz
