A character option with either a machine name that is
resolvable by DNS, or an IP address. Defaults to
localhost.
port
An integer variable with the connection port. Default
to 8194L.
default
A logical indicating whether this connection should
be saved as the default, as opposed to returned to the
user. Default to TRUE.
Value
In the default=TRUE case nothing is returned, and
this connection is automatically used for all future calls which
omit the con argument. Otherwise a connection object is
returned which is required by all the accessor functions in the
package.
Details
For both host and port argument, default
values can also be specified via options using,
respectively, the named entries blpHost and
blpConnect.
If an additional option blpAutoConnect is set to
TRUE, a connection is established in the
.onAttach() function and stored in the package
environment. This effectively frees users from having to
explicitly create such an object.
