Dear all,
For my work I usually used R to implemented processes. My idea is to crate
a workflow in Taverna using R scripts, to obtain plots or numeric values.
I followed the documentation about Rshell (
http://dev.mygrid.org.uk/wiki/display/taverna/Rshell) and I installed also
Rserve on a different machine to where I run Taverna workbench. I executed
the very easy script (eg. y <– sin(x)) and this work fine. I implemented
also a workflow with different Rshell using deparse and parse commands.
In this moment I have 2 type of problems:
1. I have created R script with a R function. Which is the semantic type to
use in the output port in Rshell service? Could be possible to use the
R-expression?
2. I have used Execute_SQL_Query Service. Which is the depth values to
obtain a result list that I can use as input in a Rshell? And in Rshell
service what kind of semantic type should I use to the input from a SQL
query?
Many thanks in advance
Alessandro
