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

[Ken Termiso]

Let me clarify the problem a bit further:

tv <- 1:11108

tdf <- data.frame(cbind(11108:1, 22216:11109))


In this example, what I would like to do is re-order the entire tdf data 
frame based on its first column (since the contents of tdf[,1] are identical 
to tv, just not necessarily in the same order in my problem, but here 
obviously the tdf data frame is already ordered the same as tv).

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

Thanks,
