I am downloading say 100 files from ucsc website and storing it into dest
folder.
download.file function create a file in destination folder even if the file
is not present which is something I dont want.
So I wrote if condition to remove the file if the download function has non
zero value.
Now it exits when there is an error or file not present. How can I use
"try" and "if" condition together so that the program does not exit on
error and delete the created file in destination folder.
for (i in 1: 100)
{
fileUrl = ucscfilenames[i]
if (download.file(fileUrl, destFile, 'wget' , quiet = TRUE) != 0)
{
file.remove(destFile)
}
}
thanks
