Hi R people.

 

I ran into this problem: I created a plot with errbars, like this:

> errbar(x=c(1,2,3,4), y=c(2,1,3,3), yminus=c(1.5,0.5,2.5,2.5),
yplus=c(2.5,1.5,3.5,3.5))

Next, I wanted to accentuate some x value with an abline, like this:

> abline(v=2)

 

In one of my R sessions (which admittedly I have had open for quite a while
now), the abline draws outside of the plotting region of errbars (till the
edge of my plotting window at least).

I tested for the cause by opening another session (clean) of the same
version of R (2.13), and running the same set of commands. In this session,
I do not have this behavior. Conclusion: I must have changed some graphical
parameter in my original session, but I don't know which one. Do you?

 

As an addendum: I also want to add a few specific axis ticks besides the
standard ones in my graph. I used axis for this, and it works. I set
col.ticks to match the color of my abline (in the nonsimplified code), and
this works too, but unfortunately, the label below the tick is not in this
color, and a parameter for this is not present in axis.

 

Suggestions for either? Note: I'm on windows 7 with R 2.13.
