Hello, I'm using R to run a acoustic analysis software called Seewave. I ask the code to extract a list of variables from my recording, and the program give ONE table for each of these. The tables consist of a two column data.frame with the time in column 1 and the frequency in column 2. However, for my purpose I need only one column with the time first and the frequency second. I tried different things but my knowledge in R is definitely too low to answer that. Thanks for your help!

Hi Thibault Please give a short example of what the data looks now like and what you want it to look like. regards Christiaan 2009/10/22 Thibault Grava <grava@unbc.ca>> Hello, > > I'm using R to run a acoustic analysis software called Seewave.

You're too vague about what you want.
Do you want to convert
time freq
1 10
2 20
3 30
to
tf
"1 10"
"2 20"
"3 30"
(use paste())
or to
x
1
2
3
10
20
30
(use c())
or ??
