Question

我有一些列通过Excel工作表在值中包含$。

 [1] "$5,656.50"  "$3,179.20"  "$1,391.40"  "$2,376.30"  "$1,476.80"  "$712.30"    "$5,327.80" 
  [8] "$3,642.70"  "$1,506.00"  "$7,923.70"  "$4,782.30"  "$1,392.40"  "$229.30"    "$1,106.90" 
 [15] "$1,553.30"  "$3,492.30"  "$4,029.40"  "$1,646.70"  "$6,013.90"  "$19,928.00" "$4,260.60"

此列中有> 10,000行，由于“$”，R会将其作为字符读取。

我试过

gsub( "$", " ", thedata$col.with.dollar.signs)

用空格替换美元符号，但它不起作用。

非常感谢任何其他想法。

Answer 1

这个可能：

substring(thedata$col.with.dollar.signs, 2)

例如：

vec <- c("$5,656.50", "$3,179.20", "$1,391.40")
substring(vec,2)
#[1] "5,656.50" "3,179.20" "1,391.40"

列包含需要替换的单位（$符号）
