我有一个 tibble，我正在努力变成一个 tibble。

我如何把它变成一个 tsibble 以便我可以用 ggplot2 绘制图形？
尝试的时候as_tsibble()
absence_ts <- as_tsibble(absence, key = absence$All Staff, index = absence$year)
它出现以下错误：
Error: Must subset columns with a valid subscript vector. x Can't convert from <double> to <integer> due to loss of precision.
