aggregate by factor
I have a data frame with two columns, a factor and a numeric. I want to create data frame with the factor, its frequency and the median of the numeric column
> head(motifList)
events score
1 aeijm -0.25000000
2 begjm -0.25000000
3 afgjm -0.25000000
4 afhjm -0.25000000
5 aeijm -0.25000000
6 aehjm 0.08333333
To get the frequency table of events:
> motifTable <- as.data.frame(table(motifList$events))
> head(motifTable)
Var1 Freq
1 aeijm 110
2 begjm 46
3 afgjm 337
