[R] graphical parameters in plot

[Angelo Canty]

I'm using plot to make a simple plot but I want to control where
the tick marks go on bot axes.  The graphical parameters xaxp and
yaxp seem to be ignored by the plot function so I tried setting them
using
op <- par(no.readonly=T)
par(xaxp=c(-2.4,-2.2,5), yaxp=c(-2500,10000,6))
plot(...)
par(op)
but they are still ignored.

Next I tried to use the axis function as follows
op <- par(no.readonly=T)
par(xaxt="n", yaxt="n")
plot(...)
axis(1,seq(-2.4,-2.2,length=5))
axis(2,seq(-2500,10000,length=6), cex.axis=0.9)
par(op)
but no axis labels are plotted.

Moving par(op) before the calls to axis causes the first call to axis to
extend the x-axis to the edge of the screen and the second call results
in a 0 being placed at the bottom of the y-axis.  

Is this a bug or is it just that it's Friday afternoon?  In any case
can someone please help me out here.

I'm using the following verison of R
platform sparc-sun-solaris2.6
arch     sparc               
os       solaris2.6          
system   sparc, solaris2.6   
status                       
major    1                   
minor    0.0                 
year     2000                
month    February            
day      29                  
language R
