Look at my.symbols in the TeachingDemos package. -----Original Message----- From: Rainer Machne <raim at tbi.univie.ac.at> Sent: Thursday, September 09, 2010 12:42 AM To: R-help at r-project.org <R-help at r-project.org> Subject: [R] plot symbol "+", but with variable bar lenghts Hi, does anybody know of some plotting function or an easy way to generate "+" symbols with individually settable bar lengths? I tried just combining "|" and "-" as pch and setting the size via cex, but that doesn't really work since the two symbols have different default lengths. Is there a horizontal | or a longer "-" available?

plot symbol "+", but with variable bar lenghts

You can also plot the +'s yourself using for example matlines: # Some data x <- 1:10 y <- 1:10 # Height and width of the crosses dx1 <- 0.1 # width in negative x-direction dx2 <- 0.2 # width in positive x-direction dy1 <- 0.2 # height in negative y-direction dy2 <- 0.3 # height in positive y-direction # Plot the data plot(x, y, type='n') matlines(rbind(c(x-dx1,x), c(x+dx2,x)), rbind(c(y,y-dy1), c(y,y+dy2)), lty=1, col="black") You could quite easily create a function for this.
