R help - Feb 2003 - horizontal high-density lines?

Hi all,

the option type="h" in plot() makes nice vertical (histogram-like)
lines. Is there a way to make similar, horizontal lines?

I can of course resort to using lines() multiple times, but i was hoping that
there is a more elegant solution.

thanks,

Yes - turn your head sideways.  But, seriously, for hardcopy plots
I have been known to rotate all the text and all the labels, and use
axis() commands to reverse the left-to-right ordering of labels along
an axis, in order to get a plot that I could turn sideways after it
was printed.

I guess you are looking for ?segments.

Hi all,

two solutions for horizontal high-density lines were suggested:

Use plot(..., type="h") and turn your head sideways. This turned out
to be a pain in the neck ;-). But it sure works!

segments() sure does the trick,

for example

y <- runif(10)
x <- 1:10
plot(x,y,type='n')
segments(x0=0, y0=y, x1=x, y1=y, col="red")


thanks for the help!

Remko
