correlating rows of two differently-sized data frames in R
Perhaps load them both and ?merge can show you the way. Michael

Hello everyone, I have two sets of data, with the following structure: DataSet1 Location Part Sample 1 Sample 2 A 1 value value A 2 value value A 3 value value B 1 value value DataSet2 Location Sample 1 Sample 2 A value value B value value C value value I would like to look at the correlations between DataSet1 and DataSet2, such that each row in Location A from DataSet1 is paired with the Location A row from DataSet2, and so forth. So far, my only ideas involve trying to copy-paste each of the rows in DataSet2 the number of times each occurs in DataSet1 on a spreadsheet before loading the sets into R; however, as I have approaching 8000 rows in DataSet2, this is clearly not a workable solution! I'm sure there's a simple solution to this, so I'm sorry if this seems like a really silly question. Thanks for your help!
