I am using a few R packages (webmining, sentiment, openNLP) to extract some sentences about a stock JPM, but running in the following error:
Error in eval(expr, envir, enclos) : could not find function "sentDetect"
Here is the codes I used and I made sure that all packages are installed. I checked the "corpus" variable and it is "a corpus with 20 text documents". I also used "library(help=openNLP)" to list all the functions in the package "openNLP" but did not find "sentDetect" in the list.
corpus <- WebCorpus(GoogleFinanceSource(stock))
sentences <- sentDetect(corpus)
Here is the running environment. Is it possibly related to the R 3.0.1 version (too new for openNLP) or 64-bit Windows system?

Thank you very much.
