R installs packages via its own command line interface.  The R packages are designed so that all you will need is R installed.

 

To install a package:

 

1.  Open an R console.  For windows you should run "Rgui.exe"

2.  From the menu select Packages > Install Package(s)...

3.  Choose a CRAN mirror close to your geographical location when given the choice.

4.  In the Packages menu find the package you need and select OK.  (Your package should be "CreditMetrics").

 

Of course all of this requires an internet connection.  This is the easiest way to install a package. Once you have the package installed go back to the R gui command line

 

library(CreditMetrics)

 

of you can do...

 

require(CreditMetrics)

 

 

NOTE:  if you are on another platform besides windows in Step 2. you may use the R command line and run the command   "install.packages()"

A blog post from 4D Pie Charts has a neat little tutorial on sneaking around workplace firewalls by masking R as an Internet Explorer clone. This can be helpful for downloading packages and using RCurl they say.

Interesting and pretty clever.
