R 删除柠檬化后的空间

我只是简单地将一个字符向量化。问题是，柠檬化在单词之间创造了一个由破折号统一的空间（例如，短期变为短期）。我的字符向量充满了这些单词，所以我想找到一种方法来消除这种失真

让我举一个例子：

text <- c("Stackoverflow is a great website where you can find great and very skilled people who are so kind to solve your coding problems. In the short-term is a very good thing because you can speed up your research, in the long-term is better if you learn how to code on your own. Let me add more non-sense to make my point. The growth-friendly composition of public finance is a good thing.")

ch_vector <- lemmatize_strings(text)

相反，我想要这个：

"Stackoverflow be a great website where you can find great and very skill people who be so kind to solve your code problem. In the **short-term** be a very good thing because you can speed up your research, in the **long-term** be good if you learn how to code on your own. Let me add much **non-sense** to make my point. The **growth-friendly** composition of public finance be a good thing."

到目前为止，我对每个感兴趣的词都是这样做的：

ch <- sub(pattern = "growth - friendly", replacement = "growth-friendly", x = ch_vector, fixed = TRUE)

ch
但是，我不确定这将如何与
textstem
包的设计用途相互作用，因此这可能满足您的需求，也可能不满足您的需求。
它工作得很好，tanks！我自己也试过了，但使用了下面的代码
sub（“-”，“-”，x）
，但它不起作用。然而，使用gsub可以很好地工作！再次感谢
ch <- sub(pattern = "growth - friendly", replacement = "growth-friendly", x = ch_vector, fixed = TRUE)


x <- "Stackoverflow be a great website where you can find great and very skill people who be so kind to solve your code problem. In the **short - term** be a very good thing because you can speed up your research, in the **long - term** be good if you learn how to code on your own. Let me add much **non - sense** to make my point. The **growth - friendly** composition of public finance be a good thing."

gsub(" - ","-",x)

# [1] "Stackoverflow be a great website where you can find great and very skill people
# who be so kind to solve your code problem. In the **short-term** be a very good thing
