When i try to run R code it states that the packages are not installed (grid and ggplot)
I have gone to the KNIME preferences and tried to change the file location from the KNIME default to my own version of R and now R is not working at all!
There are 2 main preference options related to R and where KNIME utilises R.
R
R(labs)
Which one do i change and how to do i change it so that it KNIME uses my version of R? found on my C: drive? The R version i want to use is version 3.1.0
If someone could go through a step by step example with example file paths that would great as i am not sure what i am really doing!!
<p>pointing to the jri.dll (make sure you point to x64 when using 64bit) - again this is not much information when you dont know what a knime.ini file is!!! i assume it is the file that can be read using node pad and has the following information in it:</p>
