I want avoid using "cex =" to control the size of a dash as my plot symbol in R, because it also increase the thickness of the dash line as well. Do anyone has an idea on how to use a long-thin-dash line as my plot symbol in R programming language?
Hey,
I think this give you a great explanation for your problem. In Line 30. (lty= 5) type and lwd = x is the width of the line
Just try it

look at the command: points(rep(1.5,length(x)),x,pch=-95, col = "red"), will plot the points of the vector x, with dash (-) as the plot symbol. My problem is to make the dash line wider without increasing the thickness of the line.What Leon say will not work for me.
Sorry to revive and old question. I had a similar situation come up today and a quick search brought me here. I wrote a small function that wraps around "segments()" that will plot dashes of user-defined length at given point-coordinates:
points.dash
