[R] The program can't stop when searches over all files under folders and subfolders
Hi,
I tried to convert all wma file to mp3 by av library and then I delete
the wma file. Even after all files are converted to mp3, the program is
still running. Is there anything wrong in this program?
################
library(av)
all_files <- list.files(path = ".", pattern = '*.wma',
all.files = FALSE,
full.names = FALSE, recursive = TRUE,
ignore.case = FALSE, include.dirs = FALSE, no.. = FALSE)
for(i in all_files)
{
av_audio_convert(
audio = i,
output = gsub(".wma", ".mp3", i),
format = NULL,
channels = NULL,
sample_rate = NULL,
start_time = NULL,
total_time = NULL,
verbose = TRUE
)
file.remove(i)
}

Hi John, If the program is still running, I can only guess that the function is not exiting properly. If this happened to me, I would run "top" in a terminal window and see if that process number was actually doing anything or had gone zombie.
