%description
Weather indices are formed from weather variables in this package. The
users can input any number of weather variables recorded over any number
of weeks. This package has no restriction on the number of weeks and
weather variables to be taken as input.The details of the method can be
seen (i)'Joint effects of weather variables on rice yields' by R. Agrawal,
R. C. Jain and M. P. Jha in Mausam, vol. 34, pp. 189-194,
