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.

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?
Thanks,
Rainer
