Note in R CRAN check -- * checking top-level files ... NOTE File README.md cannot be checked without ‘pandoc’ being installed

Question

I am checking my R package for CRAN submission, but there is one NOTE that I cannot get rid of. I googled it but seems this NOTE is not common thus I didn't find much useful information. Could any one provide me with a solution? Below is part of the output from R CMD check --as-cran.

* using R version 3.2.0 (2015-04-16)
* using platform: x86_64-apple-darwin13.4.0 (64-bit)
* using session charset: UTF-8
* using option ‘--as-cran’
...
...
* checking DESCRIPTION meta-information ... OK
* checking top-level files ... NOTE
File README.md cannot be checked without ‘pandoc’ being installed.
* checking for left-over files ... OK
* checking index information ... OK

Well, do you have pandoc installed? – Scanlan

Here you'll find a discussion of how to install pandoc. – Plesiosaur

@JoshuaUlrich, thanks. So we can assume that CRAN server also has that installed when checking the R package. Am I correct? – Eras

@Nussig. Thanks for the info. – Eras

You can also add the README files to your .Rbuildignore file (numerous examples of that all across github) – Crypt

@hrbrmstr, thanks. That's good to know. – Eras

Answer 1

You can install pandoc from within R using install.pandoc() from the installr package.
