This is more of a general question.

Is there any nice tutorial on how to use R in C#? Can I for instance run .txt-files with R code right from C#? Can I run R code and get the output from ggplot2 in C# for the user to look at?

The reason why I ask is that I use R at lot at work, but would like to make my analysis user friendly for colleges and customers. Therefore it would be nice to learn how to combine R with C#
