Dear R Gurus, I would like to make a line-plot of a large data-set (>200 data-points) for a document which will be printed in black and white. The plot will contain 5 different lines. So i need a way to differentiate between the lines. Since color is not an option i tried different line styles with all sorts of "line-gap" or "dot dot dot" patterns. Since my plots are rather small it is hard to get lines that look contiguous enough while still being identifiable through their line style.
What I would like to have are lines that have symbols on top of them, similar to what i get with plot(x,y,type='o'). The problem is that i have to many data-points for that method, the symbols will just "melt together", as in plot(seq(1,500), seq(1,500), type='o') - just one big line. What i want is to have a configurable number of symbols spread equidistantly over the whole graph, regardless of the number or position of data-points. Does anyone have an idea how to achieve this?
