获取有关我的数据的googleVis错误

Question

我正在尝试使用googleVis程序包来绘制数据，但出现以下错误：

Error in gvisCheckMotionChartData(data, my.options) : 
  The data must have rows with unique combinations of idvar and timevar.
Your data has 3079 rows, but idvar and timevar only define 8 unique rows.

head(mydata)

帮助我找到解决方案，我想像下面的示例一样进行绘图：

library(googleVis)
data("Fruits")
mychart<-gvisMotionChart(Fruits,idvar = "Fruit","Year")
plot(mychart)
