[R] how to make plot lines thicker

[peziza]

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.
