[R] cannot open connection: Authorization Required

2008-10-03 Thread Spencer Graves 

Hi, All:

 Is there a way in R to access a file / web site that requires
permission?

 Consider for example the following:



readLines('http://www.r-project.org/', 4)

[1] ""
[2] ""
[3] ""
[4] "The R Project for Statistical Computing"

readLines(URL) # URL = web address, which I can see via manual access. 

Error in file(con, "r") : cannot open the connection
In addition: Warning message:
In file(con, "r") :
 cannot open: HTTP status was '401 Authorization Required'


 Thanks,
 Spencer Graves
