Please be more precise. You seem not to use the rcom (note the lowercase name) package, but the RDCOMClient package which is not available from CRAN but as part of the Omegahat project.
rcom has a command comCreateObject and RDCOMClient has a command COMCreate. The code you supplied will definitely not run in with rcom. Furthermore, if your code had included the appropriate library statement, things would have been much clearer. On 4/1/2010 12:00 PM, koj wrote: > > Thank you.
