R help - Mar 2012 - climate data, Netcdf

As you can see:

time  is from 1 to 1460, 1 means they the measure Tem for the globe at the
first 6 hours , 2=after 12 hours .....; and so on 1460 *6 = 8760 hours which
equals 1 year
first of all I want to convert all data from kelvin to degree
second     I want to convert from 6 hourly  to daily and make it like this

      raw data                                what i want to make

time               temp (k)
1(6horse)        290
2                      289
3                     
4                                              1 day (min,max,averag)       
one map(file) for the globe

1460                                    365  days


so in the end will develop       365  file   for            daily min Tem
                                                     365  file   for         
daily max   Tem
                                                    365  file   for     
average  daily Tem

Thanks in advance

I am a PhD student working on global scale. I am working at INRA in France.I
am new to R

I downloaded a netcdf file           cruncep_tair_2010.nc.gz   from
http://dods.extra.cea.fr/data/p529viov/cruncep/t2m/

in this file, temperature was measured every 6 hours for 2010, I want to
convert to daily and then calculate the max ,min ,average daily temperature
I will appreciate it very much if you kindly help me. 

 How can I see the data using R, just to look at the table and then
manipulate it

I am attaching the tem for one location  45 .13 (log,lat) .(I extracted it
using GIS but I don't know if I extracted them correctly)
As you can see:

                                 365  file for            daily max   Tem
                                365  file   for        average  daily Tem

Thanks in advance
