x axis
Dear R users,
I am quite desperate for help. I haven't used R in a couple of years and I'm currently finishing a masters project and running out of time to figure out my problem. I have read and tried the examples on many websites, in your forums and R Help yet still can't manage to change the x axis. I am using R 2.8.0 on windows. 
I'm sure there must be a way to do this as many

Found this solution. It is maybe not the most elegant way, but it does the
job.

convert Factor as numeric
Dear group,
I know this issue has been already covered, and before you reply I must say
I have read the R-FAQ and search the mailing list archive.
I still can't manage to change my factor to numeric as I couldn't find any
clear answer.

using spplot (sp package) with 5 quantiles
Hi,
I'm using R 2.5.1 and gstat 0.9-39 library and I'm working with the
jura data set provided by gstat library.
I tried to plot a graph of metal concentrations (let's say Cd) with
the command spplot, but I realized that the default lags are equally
distributed between Min and Max. I did:
library(gstat)
data(jura)
jura.pred.xy <- jura.pred

spatial cross-correlation
Hi;
I cannot find in the R html documentation a way to evaluate
cross-correlation in 2D data sets.
I would like to evaluate cross-correlation in a series of moving windows
between two maps.
i,e, specify several windows inside the complete 2D spatial matrixes and
for each one ofthese windows evaluate the 2D cross-correlation (commonly
conducted in the spectral domain).
Thanks in advance and best

Thanks for your kind reply. Problem is solved. However, it's "confidence
interval / treatment comparison plot" is not taking main title. And the
fonts of axes labels can not be changed using 'cex' parameter. I will
appreciate if you could help in this matter too.

Splitting a set of vectors in a list

Please help with a basic function
Hello,
I am learning how to use functions, but I'm running into a roadblock.
I would like my function to do two things: 1) convert an object to a
dataframe, 2) and then subset the dataframe. Both of these commands work
fine outside the function, but I would like to wrap them in a function so I
can apply the code iteratively to many such objects.
