hi,
first shut down automatic axis in plot with
>plot( ...,axes=F)
then
customize your axis with
?axis
axis(side, at = NULL, labels = TRUE, tick = TRUE, line = NA,
pos = NA, outer = FALSE, font = NA, vfont = NULL,
lty = "solid", lwd = 1, col = NULL, padj = NA, ...)
you can specify what ever you want
in your case :
side=1 for x axis
at=c(0,6,12,18,24)
labels=c(0,6,12,18,24)
other way to do this with ?par : see parameters xaxp, xaxs, xaxt
best,
yves.
