hydroTSM v0.8-6 on CRAN

Tue, 28 Apr 2026 00:00:00 +0000

After two years of working mostly in sub-daily functions, the new version of hydroTSM (v0.8-6) was released on April 28th 2026, and it is available on CRAN now

Among its new features the following stand out:

New graphical logo.
New , created with pkgdown.
Package tested against R version 4.6.0 (2026-04-24) – “Because it was There”, following an imperative request made by CRAN.
New function isComplete, for identifying whether a zoo object has a regular time frequency without missing values from the first one to the last one.
New function shiftyears, to allow the computation of annual values starting in a month different from january. Mostly for internal purposes only.
The baseflow function can now apply the low-pass filter more than three times, which should be mandatory for hourly time series (Ladson et al., 2013).
The daily2annual function has a new argument ‘start.month’, to choose the starting month to be used in the computation of annual values.
The function cmv has a new argument ‘start.month’, to choose the starting month to be used in the computation of annual values.
The matrixplot several new arguments to customise the legend and the output figure.
The fdc has a new argument ’thr.pos’, to customise the position of the thresold in the output figure.
Several bugfixes.

I hope you enjoy it !.

hydroPSO v0.5-0 on CRAN

Wed, 18 Mar 2020 00:00:00 +0000

After a long amount of work, the new version of hydroPSO (v0.5-0) was released today March 18th 2020, and it is available on CRAN now

Among its new features stand out:

Full compatibility with (hydrological/environmental) models implemented as R functions (e.g., TUWmodel, GR4J, etc)
New showing how to calibrate TUWmodel with hydroPSO.
New showing how to calibrate TUWmodel with GR4J (and other models of the airGR family).
verification: now it is fully compatible with R-based models and allows parallelisation.
read_results, plot_results, read_out :much faster now due to the use of data.table::fread instead of read.table
New dataset Trancura9414001 with daily time series on P, Temp, PET, and Q from 1979 to 2016.
Package tested against R 4.0.0 (unstable) (2020-03-17 r77992) –“Unsuffered Consequences”, following an imperative request made by CRAN.

New references were added for KGE (Santos et. al, 2018; Knoben et al., 2019; Mizukami et al., 2019)
New reference was added for me (Hill et al., 2006) Thanks to Erli Pinto dos Santos !.
br2: new argument ‘use.abs=FALSE’, to allow the user to use ‘abs(b)’ as condition to decide whether using abs(b)*r2 or [1/abs(b)]*r2 in equation (5) in Krausse et al. (2005). Thanks to Ellie White !
