Hi,
I want 12 ticks at axis 1 and want to write Jan-Dec on each.

something like:

axis(1, at=1:12,
labels=c('J','F','M','A','M','J','J','A','S','O','N','D'))

I could omit default ticks but now how to control ticks.

Dear Yogesh,
I spray my clothing with "No-Bite", and that controls ticks quite well.

plot(file$time, file$ch4*1000, ylim=c(1500,1700), xaxt='n', xlab= NA,
ylab=NA,col="blue",yaxs="i",lwd=2, pch=10, type="b")#

axis(1, at=1:12,
labels=c('J','F','M','A','M','J','J','A','S','O','N','D'))

BUT above is not working, and there is no error as well.

Pls help,

Regards,
Yogesh
