Dear R and hydrological/environmental community, A major release of hydroPSO is now available on CRAN. This new release: -) implements the Standard Particle Swarm 2011 (SPSO-2011) -) is parallel-capable, to alleviate the computational burden of complex models with "long" execution time -) has an improved performance (33% - 38% faster) -) allows normalization, wh...

Dear R and hydrological/environmental community, I would like to draw your attention to hydroPSO, a newly developed R package for the calibration/optimisation of (complex) environmental models. hydroPSO implements a state-of-the-art Particle Swarm Optimisation (PSO) algorithm, which is a global optimisation technique with a surge of attention given its flexibility, ease of implementation a...

Dear all, I just installed the package hydroPSO and when I try to run the example of the lhoat() function I got this error: nparam <- 5 lhoat( fn=sphere, lower=rep(-100,nparam), upper=rep(100,nparam), control=list(N=10, f=0.1, write2disk=TRUE) ) *Error in fn.name == "hydromod" : * * comparison...

...t_results -> plot_out -> ggof -> plot2 However, if I call EXACTLY the same script from the R console, by using > source("myRscript.R") I do not get any error. As you can see in the error message, the function 'plot_results' calls 'plot_out' (both in the hydroPSO package). Then 'plot_out' calls the function 'ggof', which in turn calls 'plot2' (the latter 2 in the hydroGOF package), and 'plot2' has a call to 'hasArg'. The package 'hydroGOF' exports all its functions by using: exportPattern("^[^\\.]&qu...

This approximates the process used by Amelia (\url{http://gking.harvard.edu/amelia/}) but is much faster when filling in values for a single line of data. * hydroPSO (0.1-54-1) Maintainer: Mauricio Zambrano-Bigiarini Author(s): Mauricio Zambrano-Bigiarini [aut, cre] and Rodrigo Rojas [ctb] License: GPL (>= 2) http://crantastic.org/packages/hydroPSO This package implements a state-of-the-art version of the Particle Swarm Optimisation (PSO) algori...
