I have installed ggplot2, and when I request it in the provided sample IRIS R Script, I receive the message Warning message: In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE, : there is no package called 'ggplot2'. ggplot2 does load in RStudio. Has anyone met this problem? Thanks.
It sounds like you have more than one version of R installed on your computer, and ggplot2 is only installed in one of the libraries. Check KNIME preferences to see what path it is using for R, and run R.version() or a similar commmand in R in both KNIME and R studio to see if they are the same. If this is the problem, you can google about using a shared library for all R versions installed on your computer.
Thanks for that.
I have two active libraries namely:
"C:/Users/George/Documents/R/win-library/3.2" "C:/Program Files/R/R-3.2.0/library"
I ran R.Version() and it's the same in RStudio and Knime. Hmmm. Any other ideas - is Knime looking at both libraries?
When I issue the library() command from Knime, it only lists the packages in
The message at the top of this screen listing says "R packages available (Not Responding)" and the screen freezes. when I close it I get a message "knime.exe is not responding" with an option to Close the program. Is this a bug in Knime?
Would you know if there's any way of changing the default install library in RStudio - it's the first one above and appears to be 'burnt in' as the default? Thanks.
Just copy paste the library you have in :
"C:/Program Files/R/R-3.2.0/library" directory
Thanks for that - just did that - all fine now. Appreciated.
Use .libPaths() to get all library paths of your installation.
You can use .libPaths() to set more than one install library e.g.
Place this statement in your R snippet to get packages from both paths.
Is there a place for this statement to apply globally in every snippet?
