Random change the order of rows in a data frame

Question

I have a dataframe which have one column like this:

> df$stocks
1 stock1
2 stock2
3 stock3
4 stock4

Is there any function which changes randomly the order of rows when I execute it like the first time I execute it the result of the data frame will be:

 > df$stocks
    1 stock2
    2 stock1
    3 stock4
    4 stock3

The next time will be something different etc.

Use `sample` and basic `[row, col]` to get started. – A5C1D2H2I1M1N2O1R2T1 Jan 04 '16 at 15:33 — A5C1D2H2I1M1N2O1R2T1, Jan 04 '16 at 15:33

We can use sample

df$name[sample(nrow(df))]
