airquality數據集需要調用嗎
我這有輸入hist(airquality)
結果提示
Error in hist(airquality) : object 'airquality' not found
In addition: Warning message:
R graphics engine version 12 is not supported by this version of RStudio. The Plots tab will be disabled until a newer version of RStudio is installed.?
怎么解決呢

這個函數hist必須要帶變量吧，直接給數據集畫柱形圖不行吧
