Is there a way to have the distance between label and axis adjusted automatically? This is interesting in particular for the y-axis, when it is not known in beforehand how many digits the numbers will have. It may happen then, that numbers and label overlap.
All examples that I found work by estimating the required
distance manually in beforehand and then providing large enough
margins, or positioning the label far enough away from the axis.
I have a series of plots, that should be done automatically. They
have different magnitudes in y-direction. So there is no
universal estimation that looks good in all cases -- of course I
can provide a "safety margin", but it looks stupid when there is
too much space between label and axis.
I tried to use the relative positioning mechanism of frames,
roughly like this:
fb <- packGrob(fg,yaxisGrob(vp="dataRegion"),side="left")
fg <- packGrob(fg,textGrob("y axis label",rot=90),side="left")
But it appears that the true size of the axis is not respected;
numbers on the axis and the label still may overlap.
Can anyone provide a simple example how to do this right? I would
favor a solution using the 'grid' package.
Thank you
