I have a dataframe df

Feature Sample Value
A S1 12
A S2 15
B S1 13
B S2 11

I want to convert it to the format

   S1 S2
A  12 15
B  13 11

I don't know how to do this in R

If the second column is called `V2` you can do `data.table::dcast(as.data.table(df), ... ~ V2)` – IceCreamToucan Aug 19 '19 at 16:27
`xtabs(Value ~ Feature + Sample, df1)`. – Rui Barradas Aug 19 '19 at 16:29
