Hi there,
Sometime download.file() failed to download the file and I would like to
remove the correspond file.
The issue is that I am not able to do it and Windows complain that the
file is use by another application.
I try to closeAllConnections(), or unlink() before removing the file but
without sucess.
Any idea how I should proceed &
Please find the code below
# consider warning as an error
options(warn=2)
# try to download the file
tryCatch({
download.file(url,path_file,mode="wb",quiet=quiet)
return(0)
},error = function(e){
if(verbose){
print(e)
print(e$message)
}
# close file when it failed
if (file.exists(path_file)){
closeAllConnections()
#unlink(path_file, recursive=TRUE)
#file.create(path_file,overwrite=TRUE,showWarning=TRUE)
#system(paste0('open "', path_file, '"'))
file.remove(path_file,overwrite=TRUE,showWarning=TRUE)
}
return(1)
}
)
Thanks a lot
Cheers
Fabien
