?grid::gpar lists 'lex' as a "Multiplier applied to line width", and that seems to work when supplied as a top-level argument (though not in the parameter settings): xyplot(1:10 ~ 1:10, pch = c(1, 3), cex = 2, lex = 3) I'm not sure if 'lwd' should have the same effect (it does in base graphics). -Deepayan ______________________________________________ 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.
