   Hello,

   I have a problem, I can't install the package 'mgu74av2cdf'. I
   downloaded the zip file, yet when asked the R console to install it
   from a zip file, I got the answer:

   "Error in file(file, "r") : unable to open connection
   In addition: Warning messages:
   1: error -1 in extracting from zip file
   2: cannot open file `mgu74av2cdf/DESCRIPTION' "

   What can I do? please help me

   Thank you in advance, Yair Snir
