[R] ggplot2: problem with large fonts and overlapping labels

[Paul Emberson]

Hi,

I am using ggplot2 to generate graphs for a paper I am writing in two 
column format.  When I shrink the graphs to fit in a single column, the 
graph is clear but the axis and tick labels are way too small.

I have increased the font sizes by manipulating the grid.  However, when 
I do this the tick labels and axis labels get very close or even 
overlap, especially on the y-axis.  Is there a way to increase the 
margin between tick labels and axis labels with ggplot or by 
manipulating the grid?

Regards,

Paul
