[R-SIG-Finance] Problem when installing IBrokers from code.google.com

[me at censix.com]

Hi all

I just downloaded IBrokers from http://code.google.com/p/ibrokers  using
svn and have tried to install it by first creating a file called
"IBrokers_fromsvn.tar.gz" and then doing the usual installation from R
commandline:

> install.packages("~/sorencompile/IBrokers_fromsvn.tar.gz")
Warning in install.packages("~/sorencompile/IBrokers_fromsvn.tar.gz") :
  argument 'lib' is missing: using

inferring 'repos = NULL' from the file name

Warning message:

Q: Is this installation failing because I am missing some essential
dependencies (unlikely but possible) or is it in the way I created the
package file ? Or should I be using a different source repository for
getting the latest IBrokers package alltogether ?

Thanks for some hints.
