Entity Recognition in R error in openNLPdata

This is my first attempt as using stackoverflow and I am also still very new to R, so I apologise if I screw up any formatting.

I am currently trying to get the entity recognition commands to work in the openNLP package. using their provided examples, however I am still getting an error. please see the code below 

install.packages("rJava")
install.packages("openNLPmodels.en", repos = "http://datacube.wu.ac.at")

library(NLP)
library(rJava)
library(openNLP)
library(openNLPdata)


s <- paste(c("Pierre Vinken, 61 years old, will join the board as a ",
             "nonexecutive director Nov. 29.\n",
             "Mr. Vinken is chairman of Elsevier N.V., ",
             "the Dutch publishing group."),
           collapse = "")
s <- as.String(s)

## Need sentence and word token annotations.
sent_token_annotator <- Maxent_Sent_Token_Annotator()
word_token_annotator <- Maxent_Word_Token_Annotator()
a2 <- annotate(s, list(sent_token_annotator, word_token_annotator))

which returns as error: 

Error: Can't find `geom` called 'Pierre Vinken, 61 years old, will join the board as a nonexecutive director Nov. 29.
Mr. Vinken is chairman of Elsevier N.V., the Dutch publishing group.'
Run `rlang::last_error()` to see where the error occurred. ```

Please help me, I am so confused, as I ran it last thursday and it seemed to work, however now it doesnt. Thank you, any help is appreciated.

Solution

  • It worked for me when I removed/unchecked ggplot2 from the library.
