Look in clipboard.c in the source. It seems to use GetClipboardData. See Microsoft's site: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui/windowsuserinterface/dataexchange/clipboard/clipboardreference/clipboardfunctions/getclipboarddata.asp or just google for GetClipboardData . Its the first hit. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
