[R] ordering a data frame to same order as a chr vector

[Stefano Calza]

Hi,

if I got it right I'd suggest to use match (which would allow you to use 
also character vectors)

So

tdf[match(tv,tdf[,1]),]

will give you tdf in the same order as tv

<Ken>In this example, what I would like to do is re-order the entire tdf data

<Ken>I would like to use the vector tv to give tdf the same exact order as tv, 
<Ken>based on that first column of tdf which is identical to tv.
