Hi,
The following seems to work:
plot(1:12,1:12,xaxt='n',xlab=NA)
axis(1,at=1:12,labels=c("J","F","M","A","M","J","J","A","S","O","N","D")
)
So I'd guess that your X axis data, file$time, doesn't take the values 1
to 12.

Subject: [R] how to control ticks
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.
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
