Issue in Histogram Plotting in R

Question

I'm trying to plot histogram of sample data available in lubridate package in R. The following code i'm using to create a histogram but i'm getting an error for duration which states: Incompatible duration classes (Duration, numeric). Please coerce with as.duration . Could anyone tell what is the issue here?

library("lubridate")
library("ggplot2")
str(lakers$time)
lakers$time<-ms(lakers$time)
lakers$time <- as.duration(lakers$time)
lakers$time <-dminutes(c(12, 24, 36, 48, 53)[lakers$period]) - lakers$time
qplot(time, data=lakers, geom = "histogram", binwidth = 60)

我使用as.numeric，并使用较旧版本的R studio将这两个类都转换为数字类
