[SOLVED] Variograms revisited

Here you can report the problems encountered when using a function relative to the variography:
- experimental variography (vario.calc, vario.grid, vmap.calc, ...)
- model fitting (model.auto)

[SOLVED] Variograms revisited

Is there any way to increase the font of the variogram axis labels? It is possible to save the graphic window as a metafile and modify the metafile but do any of the native R axis commands allow increasing the font?

Sorry for this (very) late answer.

Variograms are plotted using standard graphic methods (plot, lines, ...).
The plotting method is called vario.plot() (using plot instead is simply refering to the S4 mechanism and using the generic plotting function).
This information helps in getting the information on the different arguments available.

Then if you ask for information about this method (? vario.plot), you will see that the method includes the use of "..." as argument.
This is the technique to pass (unnamed arguments to subsequent methods).
If you follow the link, you will see that ultimately, you end up with the arguments passed to the method par().
There, browsing among the various parameters, you will see that 'cex.lab' is the argument that you look for.

Finally, as a test, if you have an object containing an experimental variogram (say called 'vario'), you can perform:

plot(vario, xlab="my variogram")

which will create a graphic with standard axis annotation (or axis labels). But you can also try:

plot(vario,xlab="my variogram",cex.lab=2)

and check that the characters of the label have doubled.
The same remark holds for the label tick marks using the argument "cex.axis".
Obviously, you can also adapt for changing along the Y axis.

If this post answers your question, please make sure to modify the topic of your initial post by adding "[SOLVED]" in the title.
