Hello Joshua,
Thanks for your help. The ranking list doesn't have numbers (it
doesn't
matter the name of the file), just the file name, and the ranking
is assumed
base on the position of the file name in the list (so the first
filename to
appear is ranked number 1). So I guess I would just need to add the
filenames into a vector (array) for both rankings and then compare
them.. is
You would add both lists to vectors.
it right? And to compare them I would use cor() right?
cor() requires numeric data. To use it in this case, you would need
to come up with rankings based on the position for each file name, and
use those pairs of numbers with cor().
One possible source for such numbers would be row.names(dfrm) since by
default (assuming they are in a data.frame) row.names are an ascending
series of integers, but one could also number them by appending a
colrankn=1:nrow(dfrm).
