Hello all,

I  am trying to use "clim.pact" package for my work, but since this is  the  beginning for me to use gridded datasets in "R", I am having some   trouble. 

I want to do seasonal analyses like   trends, anomalies, variograms, EOF and probably kriging too to   downscale my 1 degree gridded data to 0.5.  So, as a first step, I   compiled my entire dataset (with 25 yeears of daily dataset which were   present as 25 files) into a single netcdf file. 

Then, I downloaded clim.pact to do further analysis, which works but  seems  to change dataset's original dimensions' order for  "retrieve.nc"   function (i.e. original lon, lat, time order was changed  to time,  lat,  lon after using this function to get a subset). I am not  sure as  to why  this happened and not able to get any plots such as box  plot  (showing  trend in "lon", "lat", "time"), variogram (or variance),   correlation  analysis done because of this conversion problem. 

Further, basic "R"  functions seem to work well with objects such as   dataframe, matrix ..etc  with time in a separate column, and the data   values (precipitation, or  temperature) in a separate coulmn with   corresponding station values  (lon/lat). So, now I have very little idea   about what I have to do. Can anyone suggest me a better (probably  more refined way) way than what I am currently doing to analyze these  data?
