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.
