I was wondering if there was a function like "does connection exists" ?
See ?showConnections.
I am currently using loops to build up a database, and I have either
B = getConnection(localization)
Error in getConnection(localization) : there is no connection -2147483648
In addition: Warning message:
In getConnection(localization) : NAs introduced by coercion
Where did the localization variable come from? getConnection is pretty
rarely used.
or
B = scan(localization)
Error in file(file, "r") : cannot open the connection
In addition: Warning message:
In file(file, "r") : cannot open: HTTP status was '404 Not Found'
is there a way to test where localization is an html page, or not ? and to
say that if localization does exist, then scan it ?
What's your definition of an html page? Testing for valid html is hard.
