In addition to following Jim's suggestion, you should probably also use
full.names = TRUE, otherwise you will try to open a connection to files
in your current directory, not in tmpdir.
Another thing is that the unzipped files appear irregular with respect
to columns, so read.table might not work too well.

What is the problem that you are trying to solve?
Tell me what you want to do, not how you want to do it.

Hi All,
I need to loop through and download the past 10 years of met data to a
temporary directory. I then need to unzip it and place it into another
directory.
year = (2005:2015)
for (i in year)
tmpdir = tempdir()
file[i] = file.path(tmpdir, sprintf('724927-23285-%4i.gz', i))
url = sprintf('
ftp://ftp.ncdc.noaa.gov/pub/data/noaa/%4i/724927-23285-%4i.gz', i, i)
#file = basename(url)
download.file(url, file[i])
files = dir(tmpdir, '*.gz', full.names=FALSE)
read.table(gzfile('files'))
'file' returns 2015 indices with "/tmp/RtmpKvB4Wz/724927-23285-2015.gz"
next to 2015. and files returns 724927-23285-2015.gz. However, when I try
to unzip the gz file using the last line, it says it cannot open the
connection and the probable reason is that there is no such file or
directory.
Thanks,
Alexandra
