I am trying to make the lines thicker in a graph (for a ppt presentation). Here is what I currently have: plot(x,y,type="l", ylab="Number of OTUs", xlab="Number of Samples Collected", col="Black", pch=1, ylim=c(0,6000)) points(x, Sobs$Chao_1_Mean, type="l", col="Gray", pch=1) (this is one of the added lines in the graph). I believe cex can help increase the size of the points. But I haven't been able to get it to work. -- View this message in context: http://r.789695.n4.nabble.com/how-to-make-plot-lines-thicker-...
