I'm not sure we can know what you mean by "confirm that MS Excel honors that OutDec." The result of options("OutDec") was intended for you to determine what character not to remove from a monetary value in an R workspace. If the assumption is that all values will be in the same unit and that the user is not doing any currency conversions then:

>  decsep <- options("OutDec")
> rmchar <- paste0( "[$£€", c(".", ",")[!c(".", ",") %in% decsep], "]" )
> gsub(rmchar, "", c("$1,000", "1,200", "800"))
[1] "1000" "1200" "800"
