Hi all,
I'm attempting to make a quite-specific plot where the axes cross at the
origin and with gridlines for guidance. I've been using ablines to create
the reference lines because I want a lot of control as to where they are
placed on the axis. This command works very well for such control.
However...
These ablines don't seem to work when I specify the origin as 0,0. They go
beyond the x-axis at both ends, rendering a quite ugly graph (and they push
back the y-axis title some).
Behold:
###
x<-c(0,1,2,3,4,5)
y<-c(0,2,4,6,8,10)
plot(x,y, axes=FALSE)
axis(1,at=c(0,1,2,2.5,3,4,5),pos=0)
axis(2,at=c(0,2,4,6,8,10),pos=0)
abline(h=c(1,2,3,4,5))
###
Is there any way for me to specify that these ablines should not go beyond
the y-axis extent? I just want a pretty graph!
Thanks!
Ryan
