Subject: correlating rows of two differently-sized data frames in R
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!
Jen
