R：如何從文本數據刪除\ n和<br />

Question

我有一個文本數據如下所示：

hold that\nagainst me. i spend most of my days trying to build cool stuff for\nmy company. <br />\n<br />\ni'm an entrepreneur (like everyone else in sf, it seems) and i love\nwhat i do. 

我用下面的命令，但它只是刪除\ n和仍然存在。

gsub("\n <br />", " ", h) 

，當我試圖此命令，無論是人物被刪除，但在實際的文本數據的「重」也將被刪除。所以，我想知道什麼是刪除兩者的正確方法。

gsub("[\n <br />]", " ", h) 

Answer 1

text <- "hold that\nagainst me. i spend most of my days trying to build cool stuff for\nmy company. <br />\n<br />\ni'm an entrepreneur (like everyone else in sf, it seems) and i love\nwhat i do." 

使用(pat1|pat2)選擇不同的模式（[]僅適用於單字符的替代品）。

gsub("(\n|<br />)"," ",text) 
## [1] "hold that against me. i spend most of my days trying to build cool stuff for my company.  i'm an entrepreneur (like everyone else in sf, it seems) and i love what i do."
