The only way I can see to do this easily is to set "tcl" to 0 in a par
call, before you do the plotting:

## from example in ?stripchart
opar <- par("tcl" = 0)
with(OrchardSprays,
     stripchart(decrease ~ treatment,
                main = "stripchart(Orchardsprays)", 
                ylab = "decrease",
                vertical = TRUE, log = "y"))
par(opar)

This is because doesn't have a "..." argument to pass to other plotting
functions like some plot functions have, and it doesn't have an 'axes'
argument to suppress axis drawing - probably for good reason.

Looking at the internals of stripchart, adding and argument tick = TRUE
to stripchart which is used in call to axis() and Axis() in the code
might do the trick.
