More detailed error messages for R templates #14

Open niederle opened 10 years ago

niederle commented 10 years ago

If a R script (or template) has a syntax or evaluation error, the message is always the same. It would be helpful to wrap the script in a try catch clause before sending it to Rserve and get the variabel storing the error in case of a failure.

error message transfer has been improved including the preference setting to use the 'evaluate' package of R. TODO: implement an R-console view for input/output/warnings/errors
