R Forwards Package development modules for women and other underrepresented groups.

R Forwards is an R Foundation task force that was originally set up in December 2015 to address the underrepresentation of women in the R community. An analysis of CRAN package maintainers estimated that fewer than 15% were women, and a useR! participant survey found that women were less likely than men to have experience contributing to or writing packages. In 2017 it was rebranded to accommodate other under-represented groups such as LGBTQI, minority ethnic groups, and people with disabilities.

Forwards have delivered face-to-face one-day workshops in Package development, supported by a grant from the R Consortium, for several years. These are heavily based on the R packages book by Hadley Wickham and Jenny Bryan. Recently we have been modularising our workshop materials to increase our reach by developing and delivering approximately one hour workshops suitable for online delivery and easy reuse by others.

Emma Rand (@er13_r) and Mine Çetinkaya-Rundel (@minebocek) are delivering the first three of these modules on 15th, 16th and 17th February. You can register using the links below. The workshops will be held on Zoom and joining details will be sent to attendees on the day.

  • explain the rationale for writing packages
