Alex -
Notice that the error message says "Error: proj_api.h not found."
Files ending with a suffix of .h are known as header files, and
on Ubuntu, they are distributed in so-called development packages,
which generally end with -dev . So I'm guessing that you installed
the proj-bin package, and now you need to install the libproj-dev
package.
You'll see the same thing for any R package that needs to be built
against an external library. Installing the library or binary is
not enough -- to build the R package you need the development files.
Hope this helps.

Dear R-helpers,
I am trying to install the package "rgdal" using the command
install.packages("rgdal")
in R. I get the following error
"Error: proj_api.h not found.
If the PROJ.4 library is installed in a non-standard location,
use --configure-args='--with-proj-include=/opt/local/include'
for example, replacing /opt/local/* with appropriate values
for your installation. If PROJ.4 is not installed, install it.
ERROR: configuration failed for package ‘rgdal’
* removing ‘/home/alex/R/i686-pc-linux-gnu-library/2.11/rgdal’
The downloaded packages are in
‘/tmp/RtmpVDlld6/downloaded_packages’
Warning message:
In install.packages("rgdal") :
installation of package 'rgdal' had non-zero exit status"
I am using ubuntu 10.10 and have installed PROJ.4 using the software
center. I have also downloaded a binary of PROJ.4 and placed it in
/opt/local/
I have looked at the documentation for "rgdal" here -
http://cran.r-project.org/web/packages/rgdal/index.html
But it seems to be about using "rgdal" as opposed to installing it.
Any help would be appreciated.
Kind regards,
Alex
