Note: Mac users must install
openNLP from source before attempting to install
This may require installing the appropriate version XTools from the Apple Developer site. You may need to register as an Apple developer. An older version of XTools may also be required.
install.packages("openNLP", type = "source")
install.packages("qdap", type = "source")
Note: Windows users may need to install
RCurl before installing
qdap. Use the following short script:
URL <- "http://www.stats.ox.ac.uk/pub/RWin/bin/windows/contrib/3.0/"
install.packages("RCurl", contriburl = URL)
Additionally, if there is a discrepency between the R and Java architectures you will have to download the appropriate version of Java compatable with the version of R you're using.
