Jorge,
This looks like an R on Windows problem, it is unrelated to VBA.
You have the statement
("source('X:\Trading\Energy\JorgeSpace\TMPholder\cpixe\home
models\toto.R')")
which is invalid R. You need to use either forward slashes or
double-back-slashes in R commands.
See the R for Windows FAQ 2.16.
Further RCOM questions should be addressed to the rcom list. You can sign
