All - I have a data frame
data.a ID valueA valueB 6 12 12 17 15 14 58 18 16 98 11 12 73 19 20 84 19 14 58 20 14 24 11 12 81 15 16 21 15 14 62 14 12 67 13 14 78 13 17 35 10 13 13 11 15 14 17 18 85 16 15 35 13 9 18 15 16 and a data frame data.b ID valueA valueB 6 84 21 78 14 I'd like to have R find the data.b$ID in data.a$ID and insert the corresponding data.a$valueA and data.a$valueB into the appropriate columns in data.b. How can I do this? Thanks for you help. SR Steven H.
