[R] [Q] Format of a plot axis label

[Prof Brian Ripley]

Do you mean the axis tick annotations, the xlab, the ylab or what? (It is 
the xlab and ylab that are quite explicitly called 'axis label' in the 
documentation.)

If you mean the axis tick annotations, please show us an example where R 
uses an unnecessary (in your view) '.0'.  The internal code uses the same 
algorithm as print.default(), and so will use the same number of decimal 
places for all the annotations on one (non-log-scale) axis.

R is very programmable, and you can use par(xaxt="n") followed by a call 
to axis(1) specifying at= and label= to get precisely what you want for 
the x axis (amend in the obvious way for the y axis).
