Dear All, Having a bit of trouble with plotting two y variables on the same graph. I cannot manage to get the secondary y axis label on to the right of the axis - it gets plotted beyond the graphic window I assume?! The way I constructed the graph is thus:
plot(data[,3],data[,2],axes=F, type="b") ## plots my data from two data colums without axes - fine axis(1, at=data[,3]) ## adds my primary axis - fine mtext("Year", side=1, line=2) ## Adds the title "Year" - fine axis(2) mtext("Index of population size", side=2, line=2) ## Puts the primary y axis on and names it correctly points(data[,3],data[,1],pch=16) ## puts my secondary y points on - also fine axis(4) mtext("Number of sun hours in April", side=4, line=2) ## if I enter "line=1" it writes over my inex numbers but if I put "line=2" it disappears. I assume that perhaps the graph automatically fills the space and does not leave any for 'odd' axes. My questions therefore are: how can I get the legend on that axis, how do I remove ylab and xlab to free the space that they take (as they spaced by default at "line=3" and thus waste space - I would like to set them to "line=2") and perhaps how do I scrunch up the x-axis so that it leaves more space at either side? Sorry for the ignorance!
