Hi
Sorry, I am clearly missing something here.
Yes, you need to use unz() for a zip file, and it does not handle urls
(only url does). So download the file (download.file()) first.
I want to read this file directly:
ftp://ftp.sanger.ac.uk/pub/mirbase/targets/v5/arch.v5.txt.gallus_gallus.
zip
I tried using
read.table(gzfile("ftp://ftp.sanger.ac.uk/pub/mirbase/targets/v5/arch.v5
.txt.gallus_gallus.zip"))
But I got an error:
Error in open.connection(file, "r") : cannot open the connection
In addition: Warning message:
In open.connection(file, "r") :
cannot open compressed file
'ftp://ftp.sanger.ac.uk/pub/mirbase/targets/v5/arch.v5.txt.gallus_gallus
.zip', probable reason 'No such file or directory'
With all the different ways of opening connections (url(), unz(),
gzfile(), gzcon() etc) I am just getting a bit lost. The above zip
archive contains a single tab-delimited file, but one which I need to
skip the first 5 lines.
Any help appreciated!
Thanks
Mick
