Mallet in R regex错误：java.lang.NoSuchMethodException:没有适合给定参数的方法

我一直在学习如何在R中使用mallet创建主题模型的教程。我的文本文件每行有一句话。它看起来像这样，大约有50个句子

Thank you again and have a good day :).
This is an apple.
This is awesome!
LOL!
i need 2.

这是我的代码：

Sys.setenv(NOAWT=TRUE)

#setup the workspace
# Set working directory
dir<-"/Users/jxn"
Dir <- "~/Desktop/Chat/malletR/text" # adjust to suit
require(mallet)
documents1 <- mallet.read.dir(Dir)
View(documents1)
stoplist1<-mallet.read.dir("~/Desktop/Chat/malletR/stoplists")
View(stoplist1)
**mallet.instances <- mallet.import(documents1$id, documents1$text, "~/Desktop/Chat/malletR/stoplists/en.txt", token.regexp ="\\p{L}[\\p{L}\\p{P}]+\\p{L}")**

根据软件包，功能应该是这样的：

mallet.instances <- mallet.import(documents$id, documents$text, "en.txt",
                    token.regexp = "\\p{L}[\\p{L}\\p{P}]+\\p{L}")

mallet.instances我怀疑问题出在你的文本文件上。我遇到了相同的错误，并使用
as.character（）
函数解决了它，如下所示：

mallet.instances您确定已将id字段也转换为字符吗？很容易忽略这些建议，而将其作为一个整数

Also there is a typo in the code sample: the backslashes have to be escaped:
    token.regexp = "\\p{L}[\\p{L}\\p{P}]+\\p{L}"
This usually occurs because the html text editor eats up one backslash.

有同样的问题，但没有解决。不知道你有什么想法。
mallet.instances <- mallet.import(documents$id, documents$text, "en.txt",
                    token.regexp = "\\p{L}[\\p{L}\\p{P}]+\\p{L}")
