Hi Milu,
My fault here. As I don't have the data to make the map and try out my
suggestions I mixed up the x and y coordinates. Try this:
par(xpd=TRUE)
arrows(-19.75966,53,33.6,53,code=3)
par(xpd=FALSE)

I've never seen the error mentioned before but see Brian Ripley's post
https://stat.ethz.ch/pipermail/r-help/2008-March/157341.html. It looks like you
are exceeding a limit.
We probably should see some sample code and data.
Please have a look at

Dear Michael,
Yes, AFAIK you are correctly reading the results.
You can print
elbow.obj$k
to obtain the optimal number of clusters, and ‘visually’ you can check it
plotting the variance vs #clusters
plot(css.obj$k, css.obj$ev)

Hi James,
If you want to specify the y-values, you need to use stat="identity" as below:
ggplot(probability, aes(x=Fertilizer, y=prob)) +

If you generate the list of pages you're comfortable editing, the posse
of folk who have already come forward can select one that we think can
be improved and see how we get along with it.

Using the first example from ?dbFD

If you look at that help page, or at str(ex1), you'll see that the

There is a two-headed arrow on the image you sent, and it seems to be
