This function can be applied to either raw or homogenized daily data.
Raw data are read from files ‘VAR_YEAR-YEAR.dat’ and ‘VAR_YEAR-YEAR.est’, and monthly data will be saved to files ‘VAR-m_YEAR-YEAR.dat’ and ‘VAR-m_YEAR-YEAR.est’.
Homogenized data are read from ‘VAR_YEAR-YEAR.rda’. In this case monthly data will be saved to files named ‘VAR-mh_YEAR-YEAR.dat’ and ‘VAR-mh_YEAR-YEAR.est’.
This function does not return any value.

#First we must generate the input files from example data:
data(Ttest)
write(dat,'Ttest_1981-2000.dat')
write.table(est.c,'Ttest_1981-2000.est',row.names=FALSE,col.names=FALSE)
rm(dat,est.c) #remove loaded data from memory space
#Now we can apply this function to these monthly precipitation data:
#
dd2m('Ttest',1981,2000)
