[R] Changing X axis values

[Amelia Marsh]

Dear Sir
Thanks a lot for your great help. I had tried the argument by = 1000, but wasn't aware of "seq". Thanks again.
With regards
Amelia

 Hi Amelia,The usual way is:
plot(...,xaxt="n")axis(1,at=seq(0,18000,by=1000)
However, you will get overlapping labels unless you use a small font or a large graphics device. You may want to look at the staxlab function in the plotrix package.

Dear Forum,

Assuming I need to plot a graph. In the code I have defined X axis range as



xlim=c(0,18000)


In the plot, the values visible w.r.t X axis are 0, 5000, 10000, 18000.

To improve the graph clarity, is there any way I can show the values of X axis as 0, 1000, 2000, 3000, 4000, 5000 .......18000 i.e. the values increase by 1000 instead of 5000.

Regards

Amelia
