datsubset: Subset Climatol input data into new files
In climatol: Climate Tools (Series Homogenization and Derived Products)

Description Usage Arguments Details Value Examples

This function allows saving a subset of Climatol input data into new input files, by selecting a subperiod and/or series with a minimum number of years with data.

1	datsubset(varcli, anyi, anyf, anyis=anyi, anyfs=anyf, minny=NA)

`varcli`	Acronym of the name of the studied climatic variable.
`anyi`	Initial year of the data present in the file.
`anyf`	Final year of the data present in the file.
`anyis`	First year of the output subperiod. (Defaults to `anyi`).
`anyfs`	Last year of the output subperiod. (Defaults to `anyf`).
`minny`	Minimum number of years with data to retain the series.

Climatol homogenization requires that no time step be totally void of data in all stations simultaneously. This function allows subsetting already existing Climatol input files by selecting a subperiod and/or stations with a minimum number of years with data (may contain gaps).

This function does not return any value.

#Set a temporal working directory and write input files:
wd <- tempdir()
wd0 <- setwd(wd)
data(Ptest)
write(dat,'Ptest_1951-2010.dat')
write.table(est.c, 'Ptest_1951-2010.est', row.names=FALSE, col.names=FALSE)
rm(dat,est.c) #remove loaded data from memory space
datsubset('Ptest',1951,2010,1971,2000,20)
#Return to user's working directory:
setwd(wd0)
#Input and output files can be found in directory:
print(wd)
