Hi all,

I'm working on a function that reads online data that is only available to certain IPs. It then writes a subset of the data into a file.
So whenever I'm logged in elsewhere or am not connected to the internet, I get an error, and the function is terminated.
I want it to rather print a message into the file.

Is there any way to test whether a connection can be opened?
Analogous to isOpen something like canOpen...
Or would I want to look into the error handling options?

By the way, the data is the internet volume used so far, which I want to track regularly (on every R-Start via Rprofile).
My brother (a computer schientist in progress) did not know a solution, so I set out to try this with R - which I got to work fine (except the above mentioned). 
"R beats java", I told him, to which he responded nothing ;-)
Isn't it amazing, what one can do with R?

Thanks ahead,
Berry Boessenkool
