I've the following data from a data frame
我从数据框中得到以下数据
Name,JoiningDate,AmtPaid
Joe,12/31/09,1000
Amy,10/28/09,100
John,05/06/10,200
The Joining Date is coming in as a factor (when I sapply). How can I convert this to date and then sort on JoiningDate?
加入日期是一个因素（当我开心时）。如何将此转换为日期然后对JoiningDate进行排序？

This should do it (where df is your dataframe)
这应该这样做（其中df是你的数据帧）
df$JoiningDate <- as.Date(df$JoiningDate , "%m/%d/%y")
df[order(df$JoiningDate ),]
