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?
