Hi All,
I have two data frames. The first contains data about a number of individuals,
coded in the first column with a name, in an order I find convenient.
The second contains different data about the same indivduals, in a different
order. Both data frame have the individual names in the first column.
I need to reorder the second data frame so the rows are rearranged in the same
manner as the fist. How?
I cannot turn the individual names in a numeric vairable with
as.numeric(data1[,1]), because the two data frames are subset of different data,
so the the factor levels are way off between the two. I think I need to actually
use the names as a index.
Cheers,
Fede
