Hi,



I have a a vector  and a data frame with two columns

vec = c("C", "A", "B")

dataDF = data.frame(A1 = c("B", "A", "C"), A2 =
c(1,2,3))



I would like to sort the data frame by column A1 such that the order of
elements in A1 is as the same as in vec.



After the ordering, the data frame would be

A1           A2

C             3

A             2

B             1



Any suggestions would be appreciated.



Thanks in advance



Jeff
