Assuming you have data in the Windows clipboard (for example, copied data from Excel), to put that data into a variable named copdat
in R use:
copdat <- read.delim("clipboard")
If you want to copy data from an R variable named rdat
into the Windows clipboard (for example, to copy into Excel) use:
write.table(rdat, "clipboard", sep="\t", row.names=FALSE, col.names=FALSE)
