Writing audio files (.wav) in a different directory

Hi.

I'm trying to export a .wav file using the writeWave function from
tuneR
package in a different folder than the default getwd().
After reading through the manuals of some audio packages I couldn't
figure
it out.

I'm picking one 3-hour .wav file and asking the function to take a
sample
of 1 minute (from minute 100 to minute 101 of the 3-hour file) and
saving
it in an object "rec".

Here is what I'm doing:

filename<-"QUm0B24x_SMS05_20100831_052100.wav"
min.ini<-100
min.fin<-101

library(tuneR)
rec<-readWave(filename,min.ini,min.fin,"minutes")
writeWave(rec,"cut1.wav")

It is writing the file in the same directory of the "filename" object.
What
I want to do is to write the "cut1.wav" file in a different folder.

Any suggestions?

Thanks in advance!

Put the directory name into the filename string. The syntax for doing that is somewhat OS dependent, but for most cases you can use "/" as the separator. You really should Google "file path" and your OS and learn how to do this, because it is broadly applicable outside of R (not an R-help question). Look for info on "absolute path" and "relative path".
