I'm new to R, so this might be a stupid question but I'd appreciate any help.
Can you execute code on a .md file? I know that you can include code, but it doesn't show the output like it does in a .Rmd file. Am I doing something wrong?
Thanks!

I know this is an extremely basic question, but someone suggested i try running a code from github and I have no idea how to go about it
I tried copying and pasting but that didn't work and neither does downloading it and trying to open it with R.
You can click the raw button on github to get the url

I want to trigger R code from an excel spreadsheet. I couldn't find any options other than Rexcel. Is there any alternative or simpler way to do this (may be use VBA)?
In VBA you can call any command line programs, so you can call R in batch mode.
Call Shell("R --vanilla scriptfile.R outputfile.txt")
