[R] Help update.packages()

[Dinil Penne]

I'm getting the following error message - 

> update.packages()
The name specified is not recognized as an
internal or external command, operable program or batch file.
Error in download.file(url = paste(contriburl, "PACKAGES", sep = "/"),  : 
        No download method found
In addition: Warning messages: 
1: wget not found 
2: cmd execution failed with error code 1 in: shell("lynx -help", invisible
= TRUE) 


Could someone explain what may be going on and/or how I can fix the problem?

Thanks in advance.

Samir.
