Dear all, version 1.2-2 of package NMOF is on CRAN now. NMOF stands for 'Numerical Methods and Optimization in Finance'. The package provides R code and datasets for the book with the same name, written by Manfred Gilli, Dietmar Maringer and Enrico Schumann, published by Elsevier/Academic Press in 2011. The package has finally crossed the 1.0 line: It is 10 years since the development

There is also the package solrad that might do some of this. It is more intended for calculating solar radiation, which is probably not what you want, but may do other things you may find helpful. > On Jan 30, 2024, at 5:44?AM, Enrico Schumann <es at enricoschumann.net> wrote: > > On Tue, 30 Jan 2024, Richard O'Keefe writes: > >> Given >> - UTC timestamp

See, I have built my own genetic algorithm already and tested it on this problem. I have a solution, but due to the heuristic nature of GA, I cannot guarantee that it is the optimal subset. If I was simply doing this for a company project, you are spot on with the type of algorithm I would use, but I am doing this for a scientific paper. I need to be able to find the optimal subset over my

In the first paragraph of Sweave.Rnw (./src/library/utils/vignettes/Sweave.Rnw), it reads for literate programming \cite{fla:Knuth:1984}. but probably should be for literate programming \citep{fla:Knuth:1984}. ^ kind regards Enrico -- Enrico Schumann Lucerne, Switzerland http://enricoschumann.net

Just as one more datapoint: I cannot reproduce the segfault, with R 3.5.1 on (L)Ubuntu 18.04.

(Re-)read the discussion of indexing (both `[` and `[[`) and be sure to get clear on the difference between matrices and data frames in the Introduction to R document that comes with R. There are many ways to create numeric vectors, character vectors, and logical vectors that can then be used as indexes, including the straightforward way: df[ c( "Unique to strat ", "Unique
