[R] passing username and password to source()

[[Ricardo Rodriguez] Your XEN ICT Team]

Please, is it possible to pass an username and a password to source() to 
access code stored in restricted access web server?

I know I can use commands like...

 > source("http://mire.environmentalchange.net/~webmaster/R/3Dsurface.r";)

but I am not able to find if it is possible to pass authorization 
parameters together with the link.

Thanks you for your help,

Ricardo
