Hi,

I would like to change the size of my axis in order to make all my data fit in the graphic, I am using the function plot() for drawing an species acccumulation curve. Thanks in advance.

Use xlim=c(lower,upper).

E.g., if you want your xaxis to go from zero to 100:

yourplot <- plot(x=x,y=y,xlim=c(0,100))

displaying mantel r results graphically

I have carried out several mantel tests on some genetic data in 'R' and would like to plot the results in the form of a histogam of the distribution - and preferably one that shows the critical 'r' value.
The tail end of my procedure is shown below - I just need help to dig out an instruction to follow on from this result.
