I'm developing a web application that should interact with some R scripts and I would very much like to use openCPU. However, I do not see if there is any way I can do other AJAX requests besides calling the R scripts or fetching their results.
I need to send R script descriptions and other stuff which can change so it has to be done in runtime by requests to server.
If anyone would be kind enough to briefly explain if this is possible, I would be very grateful.
I'm assuming when you say update descriptions that you mean the DESCRIPTION file that acts as the definition of the R package itself. When you change this or the contents of the R script, you will need to publish a new version to Open CPU. A few notes from my experience, which seems similar to yours:
I have had some trouble having scripts running inside of OpenCPU install packages that are in CRAN but not available in the OpenCPU package list. OpenCPU can pull packages in from Github using the install_github function found in the devtools package. You might have to manually install in your R script using install.packages if your script is using an R function that the public OpenCPU doesn't have. This might be helpful if calling library or install.packages by itself doesn't work.
library('devtools') install.packages("BIOMASS", repos = "https://cran.opencpu.org", method = "libcurl") library("BIOMASS")
The list of installed packages on the public OpenCPU is here If you are using another package that is available on CRAN, you will need to add it as a dependency in your Imports section in the R package DESCRIPTION file. You can also use namespacing to avoid having to use PACKAGENAME::FUNCTIONNAME in your script.
