C’mon, i’ve only just started – this will take a while to populate. And I will probably write them as separate subpages before it all gets just too much.
I use the software platform ‘R‘ almost exclusively for my analyses, run through the R Studio front end, both on windows and mac OSX. Easiest way to get the bulk of the packages you need is to use CRAN Task Views.
For publication-quality graphs and such, I use OriginLab and Igor Pro. You have to pay for these, but they do come up good.
