R,将多行文本数据帧合并为一个单元格

Question

我有一个文本数据框,如下所示.

> nrow(gettext.df)
[1] 3

> gettext.df
 gettext
 1 hello,
 2 Good to hear back from you.
 3 I've currently written an application and I'm happy about it

我想将这些文本数据合并到一个单元格中(进行情感分析),如下所示

> gettext.df
  gettext
  1 hello, Good to hear back from you. I've currently written an application and I'm happy about it

所以我使用下面的代码折叠了单元格

paste(gettext.df, collapse =" ")

但似乎它使这些文本数据成为一个块(作为一个单词),所以我无法逐字扫描句子.

有没有什么方法可以将这些句子合并为一个句子集合,而不是将其转化为一个大字块？

Answer 1

在使用之前,您必须将数据框列转换为字符向量paste.

paste(unlist(gettext.df), collapse =" ")

返回:

[1] "hello, Good to hear back from you. I've currently written an application and I'm happy about it"
