我有一些列。它们都有数值，但是当我在R中导入它们时，它们似乎是一个字符数据类型。我想将这些字符转换为整数，并从具有它们的列中删除％符号

    $Budget(chr)"3,000.00", "2,000.00", "2,000.00"...  
    $Impressions(int) 0, 0, 0, 0...  
    $Interactions(int) 0, 0, 0...  
    $Interaction.Rate(chr) "0.00%", "0.00%", "0.00%"...  
    $Avg..Cost (dbl) 0, 0, 0, 0, 0, 0, 0...  
    $Cost(chr) "0", "0", "0", "0"...  
    $Clicks(int) 0, 0, 0, 0...  
    $CTR(chr) "0.00%", "0.00%", "0.00%"...

我尝试过这样做，但没有结果却给了我错误：

警告消息：在eval（替换（expr），envir，enclos）中：NAs 强制引入

任何人都可以帮助我解决这个问题

您可以使用transform将其转换回numeric。

transform(mData, Budget= as.numeric(Budget), Interaction.Rate = as.numeric(nteraction.Rate), ...)

要删除,和%，请使用gsub（从here获得想法）

 mData$Budget<- as.numeric(gsub("," ,"" ,mData$Budget))

如何将具有char数据类型的数字值转换为numeric数据类型
