It's not easy.  Best would be to convince caTools to add a NAMESPACE.

But as a workaround:

caToolsEnv <- as.environment("package:caTools")
LogitBoost <- caToolsEnv$LogitBoost

Note that there is no guarantee that LogitBoost will actually work. 
Because caTools doesn't have a NAMESPACE, there is a risk of other name 
clashes causing LogitBoost to behave unpredictably.
