La Quinta del Sordo. Todo el proceso ha sido independiente, y lo realizaron en su local de ensayo (discoburro.com) con software libre (Linux, Ardour, plugins LV2) . Los temas fueron compuestos por José María Sánchez (Profe) y Rafael Solsona (Teclas), y los demás músicos que participaron en esta aventura musical fueron Carlos Jalao (batería) y Adolfo Medina (bajo).

@libreoffice We still see people recommending Excel and throwing around those "Excel tools" (aka spreadsheets with some formulas).
Please stop endorsing spreadsheet apps for anything else than spreadsheets. Better use applications for numerical computations like #NumeRe or #R, which produce understandable, mainainable and debuggable solutions.
This lesson mentions '#-' comments. Is that a special kind of #R comment that I don't know about?

Your project, python/R module/library, and install package should all use the same syntax/name/capitalization.
I will die on this hill. Just stop it.
Some #R #rstats about the packages on the repositories: #CRAN has 722 packages that use Bioconductor (3%), #Bioconductor has 2802 packages that use CRAN's packages (77%).
1.3% CRAN and 0.6% Bioconductor respectively use package outside these two repositories. But 91% and 93% use packages on their respective repos. 8% and 3% do not have any dependency on external packages (but could depend on system dependencies).

#statstab #312 {presize} pkg: Understanding Precision-Based Sample Size Calculations

I'm starting to think letting statisticians do OOP is a bad idea. This r function uses a complex data type as input, but the maintainers of the package that defined that type have changed the structure of the data type, so now I have to jump through some hoops to create an object of the old type. Got to really suck for all the r programmers who don't have a CompSci background.

"Copula Additive Distributional Regression Using R"
By Giampiero Marra, Rosalba Radice
Routledge & CRC PressCopula Additive Distributional Regression Using RCopula additive distributional regression enables the joint modeling of multiple outcomes, an essential aspect of many real-world research problems. This book provides an accessible overview of this modeling approach, with a particular focus on its implementation in the GJRM R package, developed by the authors. The emphasis is on bivariate responses with empirical illustrations drawn from diverse fields such as health and medicine, epidemiology, economics and social sciences.
