I am aware of the most basic stuff, especially vectorization and subscripting.
I only gave a simple example with length 4. I need to do that for vectors of length 190. Are there any in-built commands? Or should I write the loops myself? Thank you. -- View this message in context: http://r.789695.n4.nabble.com/summation-coding-tp4646678p4646705.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
