I would greatly appreciate some example of correct usage of function unz.
I have to download and uncompress the following web compressef file:
ftp://ftp.sanger.ac.uk/pub/mirbase/targets/v5/arch.v5.txt.homo_sapiens.zip
I tried the following command that does not work:
Targets.rec <- readLines(zz <-
unz("ftp://ftp.sanger.ac.uk/pub/mirbase/targets/v5/arch.v5.txt.homo_sapiens.zip"))
Thank you in advance,
Maura

This means that you would first need to know the name[s] of the file[s] archived in the .zip file, as far as I can see. So, in that case, a first step would be to download the .zip file anyway, to your local system, and then, in whatever way is appropriate for your system ("unzip -l ...." in Linux), find out what the files in it are called. But once you have got that far, you may prefer to handle the .zip file outside of R ...
