Dear R users, I have been trying to estimate global sensitivity indices such as the sobol 1st and 2nd order indices. I managed to obtain the PRCC. The example presented in the sensitivity package on sobol2002 seems to work well for linear models: for example: calculate y for given x values. However, when trying to apply this technique to dynamic models (SIR type), the error messages just keep spinning from one angle to another. Even the decoupled approach still gives errors. These may be likely due to...

...plex designs for Morris method (function morris) * multidimensional Sobol indices (function sobol) * argument return.var in sobol methods in order to have local variables which are not saved in the output object, for example the bootstrap replicates (functions sobol and sobol2002) * template files writing (function template.replace) * new argument ylim to control the ordinate axis for graphics (src, pcc, sobol, sobol2002, fast) Small changes in the functions: * several names of parameters and variables in the objects have changed * function...
