seas-package {seas} | R Documentation |
The seas
package for the R programming environment is capable of
conveying descriptive statistics and graphics for seasonal variables, as
found in climatology, hydrology and ecology. Seasonal variables can be
continuous (i.e., temperature) or discontinuous (i.e., precipitation).
An annum can be partitioned into many arbitrary divisions, or seasonal
components, such as by month or into other fixed
intervals. Boxplots are used to describe the seasonal distributions of
continuous variables. Discontinuous variables need to be summed over
time to smooth the irregularities before the variable can evaluated and
visualized. Statistics, such as precipitation normals, may be derived
from the summed variables, using the mean or median methods. Other tools
and utilities provided in the package can calculate precipitation
interarrivals, cumulative precipitation departures, find changes between
two normals, and import data from archive formats.
To get started, try some examples, such as seas.sum
,
seas.norm
. There will be more help added here someday! In
the mean-time, please explore the various help pages and try the
examples. Contact me for basic help and/or suggestions!
