在 R 中删除以 \n 或 \U 开头的字符串

Question

我有这样的字符串：

x <- c("saw the revenant awesome experience must be seen on a big theatrical screen\ntherevenant","a lil sumn sumn i whipped up \U3e64653c\U3e30613c\U3e64623c\U3e64653c\U3e36623c\U3e61383ctherevenant")

如何使用 gsub() 删除 R 中以 \n 或 \U 开头的所有内容？

Answer 1

您可以使用 iconv 删除 \U 字符并使用 gsub 处理换行符。

x <- c("saw the revenant awesome experience must be seen on a big theatrical screen\ntherevenant","a lil sumn sumn i whipped up \U3e64653c\U3e30613c\U3e64623c\U3e64653c\U3e36623c\U3e61383ctherevenant")

> iconv(gsub("\n", " ", x), to="ASCII", sub="")
[1] "saw the revenant awesome experience must be seen on a big theatrical screen therevenant"
[2] "a lil sumn sumn i whipped up therevenant"
