uneven spacing on axis with R

Question

I have a problem in plotting uneven scale plot on x axis with R

Here is an example:

plot(1:100,1:100)

will give the equal tick spac

Answer 1

For a logarithmic axis, use:

plot(x,y,log="x")  ## specifies which axis to put on log scale

For determining how many "tick marks" to use, check

par()$lab

Default is 5,5,7. To put more x axis labels, do

par(lab=c(10,5,7))

And for y:

par(lab=c(5,10,7))
