我正在嘗試在對其進行操作之前清理文本資料，并且即使我嘗試使用 gsub 專門針對它，然后嘗試小寫時拋出錯誤， ? 符號仍然沒有被洗掉。
normalize_name <- function(name){
normalized_name <- gsub("[^[0-9A-Za-z][:blank:]]", "", name) #Removes special characters and spaces
normalized_name <- gsub("?", "", normalized_name)
normalized_name <- tolower(normalized_name)
return(normalized_name)
}
uj5u.com熱心網友回復：
嘗試這個
normalize_name <- function(name){
normalized_name <- gsub("[^[0-9A-Za-z][:blank:]]", "", name) #Removes special characters and spaces
normalized_name <- gsub("\UFFFD", "", normalized_name)
normalized_name <- tolower(normalized_name)
return(normalized_name)
}
