这是我第一次尝试使用stackoverflow，而且我对R还是很陌生，因此如果搞砸了任何格式，我深表歉意。

我目前正在尝试使实体识别命令在openNLP软件包中工作。使用他们提供的示例，但是我仍然遇到错误。请参见下面的代码

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))

返回错误：

Error: Can't find `geom` called 'Pierre Vinken,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. ```

请帮助我，我很困惑，因为我上周四运行它，它似乎可以运行，但是现在不行了。 谢谢您的帮助。
