The help file for grid.line.to says that Grid has the notion of a current location. Is there a way to get that current location? I looked for a function that returns this but I didn't find anything.
Basically, I'm looking to do something like turtle graphics and I need to write a function like grid.line.to but where the endpoint is defined relative to the current location (i.e. grid.line.to.rel(-1,0) would draw a unit line left from the current location). ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
