Currently, the connection code does not include the URL in the warning message when a 404 response is received:
myUrl = "http://www.r-project.org/ABadPage.html"; con = url(myUrl) readLines(con)
Error in readLines(con) : cannot open the connection In addition: Warning message: cannot open: HTTP status was '404 Not Found'
Would it be possible (and desirable) to include the URL in the warning message? Here's an example:
Error in readLines(con) : cannot open the connection In addition: Warning message: cannot open 'http://www.r-project.org/ABadPage.html': HTTP status was '404 Not Found'
It is part of `con':
con
description "http://www.r-project.org/ABadPage.html"; class "url" mode "r" text "text" opened "closed" can read "yes" can write "no"
Remember R is an interactive system: you just need to ask it for the information you want.
This would be tedious to add, but you could submit a patch (remember there are at least three places to look at in the internet code).
