The following code works well:
library(rlc)
openPage( layout = "table2x2", useViewer=FALSE )
However, if JsRCom is loaded after rlc, this throws an error:
Error in openPage(layout = "table2x2", useViewer = FALSE) :
unused argument (layout = "table2x2")
Not sure if there's a way to fix this other than smart users but thought I'd report it.
Cheers,
Felix
