Dear David, The package doesn't have an option to customize the output of the trace.
However, you can create a custom version of the package that doesn't print the parameters. Get the package source code, uncompress it, and find the file de4_0.c in the src/ directory. Then comment out the calls to Rprintf that print the parameter values, to read: Rprintf("Iteration: %d bestvalit: %f bestmemit:", i_iter, t_bestC); // for (j = 0; j < i_D; j++) // Rprintf("%12.6f", gt_bestP[j]); Rprintf("\n"); Then re-build and re-install the package (instructions are at http://cran.r-project.org/doc/manuals/r-release/R-exts.html#Checking-and-building-packages ).
