删除标点符号和数字,以成为<U+200B>Chandler
。这是我目前正在尝试的方法:
Chandler
但是,更改“ df”中“ city”列中的单元格无济于事。当我搜索typeof(df)时,我得到“列表”。这可能与它有关吗?
任何帮助将不胜感激。
答案 0 :(得分:0)
第二个问题,tyepof()
将始终为数据帧返回list
,因为data frames are really just lists of equal length vectors。
对于第一个问题,似乎您的数据中包含一些Unicode编码的字符。照顾这些的一种好方法是将它们转换,例如:
df$city <- iconv(df$city, 'utf-8', 'ascii', sub = '')
还可以gsub
十六进制代码中的字符,如下所示:
df$city <- gsub('\u200B', '', df$city)
甚至是范围:
df$city <- gsub('[\u2000-\u20ff]', '', df$city)
但实际上我认为iconv
方法是必经之路。在这种用法中,它只会删除角色而不是渲染它,但这似乎就是您想要的。
