I am (still) translating long R scripts to FORTRAN to improve speed. My client deals with river's flow. He has datas for each day of a week, we need to 'disaggregate' them to an hourly base (is that clear ?) . In R, he uses function td of library tempdisagg with the 'denton-cholette' algorithm. I would like to translate this function in FORTRAN. I searched for denton-cholette on internet but only found 'mathematical answers' I am not able to understand. I would like to have some informations about this function : Is it only a 'wrapper' to a C or Fortran library or is it a true R function ? Is the source (R, Fortran, C, ...) available somewhere ? Thanks in advance for all information you can give me !

It is R. Source of the tempdisagg package can be found on CRAN: https://cran.r-project.org Follow the link "Packages" and then "Table of available packages, sorted by name". Direct address for tempdisagg: https://cran.r-project.org/web/packages/tempdisagg/index.html The source for the full package will be in the .tar.gz file. Berend Hasselman
