R 中的 Gsub 函数
Gsub function in R
我有下面这句话：
trying <- 'Happy CNY to You <-U+2661> Abundance BLESSING to you and your family! <-U+2661> happy and blessed year ahead! '
我想删除这句话中的所有 <.....> 个实体。我使用了以下功能：
comment = gsub(pattern = "<.*>", replacement = "", x= trying)
然而，我被退回了：
"Happy CNY to You happy and blessed year ahead! "
我可以知道如何编辑代码，以便我将拥有以下内容：
"Happy CNY to You Abundance BLESSING to you and your family! happy and blessed year ahead! "
因为正则表达式匹配是贪婪的。您可以在表达式中添加 ?。
comment = gsub(pattern = "<.*?>", replacement = "", x= trying)
