Colleagues,
I have two data frames which look like this.
Data frame 1
Serial Pre.Hole Pre.flow Pre.Date
1 3036 1 0.24 19-Nov-19
2 3036 2 0.212 19-Nov-19
3 3036 3 1.292 19-Nov-19
4 3036 4 0.262 19-Nov-19
5 3036 5 1.291 19-Nov-19
6 3036 6 0.26 19-Nov-19
Data frame 2
Serial Post.Hole Post.flow Post.Date
62323 11024 44 -0.678 11-Dec-19
62324 11024 45 -0.659 11-Dec-19
62325 11024 46 -0.654 11-Dec-19
62326 11024 47 -0.699 11-Dec-19
62327 11024 48 -0.671 11-Dec-19
62328 11024 49 -0.687 11-Dec-19
What I want is to create a data frame whose serials numbers are common to data
frames 1 and 2.
The resulting data frame 1st row would look like this.
Serial Post.Hole Post.flow Post.Date Pre.Hole
Pre.flow Pre.Date
Any ideas on how to do this would be appreciated.
