How to set up line type in plot.xts?

Question

I have multiple (about 10) time series and I want to draw lines using plot.xts. I don't know how set up types of line, i.e., dashed line, solid line, etc., in the function of plot.xts. I do have found some discussions on color setting but without any findings on this issue. Can anyone give me some hint or directions?

Answer 1

visual parameters of plot you should know are

lwd - width of the line

lty - 1 = solid , 2 = dashed , 3 = dotted.

if you want to draw multiple lines on the same graph plot the first one using plot and the others using lines.
