制作一个直方图,其频率是行中的值

Question

如何制作直方图,以便下面的每一行用条形图表示？例如,x轴"2012-10-02"和y轴"126","2012-10-03"和y轴"11352"......等等.

'date'变量是Date矢量.

         date steps
1  2012-10-02   126
2  2012-10-03 11352
3  2012-10-04 12116
4  2012-10-05 13294
5  2012-10-06 15420
6  2012-10-07 11015
7  2012-10-09 12811
8  2012-10-10  9900
9  2012-10-11 10304
10 2012-10-12 17382

谢谢

这不是直方图.您已经按日期汇总了计数.

barplot(df$steps, names = df$date,
        xlab = "Date", ylab = "Steps",
        main = "Your title here")
