I have installed RGTk2 to satisfy other package requirements.
I am not planning to use it in my own work.
Occasionally I search through the R help using the help.search() function,
and every time it returns me lots of references to the functions in the
RGtk2 package, which I don't need.

Latitude-longitude grid also could be added by generating desired polylines
in lat-lon and converting them to the desired projection using

I also have written some bindings from R to the SNNS (Stuttgart neural
network simulator), however, they are still not on the release stage.

Here is the discussion about the function search.path()
http://finzi.psych.upenn.edu/R/Rhelp02a/archive/34411.html
which searches the PATH variable for your script and returns the full path.
You also can put your script contents in functions, then create a package
and load it with library().

Background:
I have five multiple imputed datasets. For each datasets I have run a
regression analysis and combined the regression coefficients according to

You can use
plot(y~x,col=color.index.in.palette.defined.from(z),pch=20,type=p)

color.index.in.palette.defined.from(z)
is a function or an expression, returning either a color index in a
predefined palette or any other color representation, suitable for R. This
is described in ?par.
