Writing audio files (.wav) in a different directory

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".

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!
