Hello everybody, I'm testing the randomForest package in order to do some simulations and I get some trouble with the prediction of new values. The random forest computation is fine but each time I try to predict values with the newly created object, I get an error message. I thought I was because NA values in the dataframe, but I cleaned them and still got the same error. What am I

> The dangerous part of this is that characters are integers, so "foo" + 'x' is very likely to cause serious problems. std::string already provides such overloads though, doesn't it? So the code isn't any safer from accidental "foo" + 'x' expressions that don't include Twine/StringRef/std::string than it was before. But if the argument is that

wine version 20001002 running in rh7. installed and working. Have a newbie question about command line paths to access windows apps. No problem accessing anything in c:\windows eg freecell.exe by the simple command # wine freecell.exe the mount directory is named /dos (and is in /etc/wine/wine.conf under Drive c) so I assume that the command # wine /dos/agent/agent.exe should bring up the
