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] "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01
Transitional//EN\">"
[2] "<html>"
[3] "<head>"
[4] "<title>The R Project for Statistical
Computing</title>"
> 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
