Writing R packages (Fabian Scheipl)
Wednesday, February 12, 2014 (14-18 h)
Thursday, February 13, 2014 (9-13 h)
Abstract:
Applied data analysis requires efficient use and mastery of
modern software tools. In this tutorial, you'll be exposed to
programming techniques that allow better control of your working
environment in R and will enable you to implement your own ideas
in software and share them with others.
Prerequisites:
Experience with data analysis in R, basic familiarity with R syntax
Installed software:
Recent RStudio (or any other IDE of your choice), R > 3.0 with
package 'devtools'. Windows users should have 'Rtools' installed,
available here:
http://cran.r-project.org/bin/windows/Rtools/installer.html.
The tutorial is supported by the Center for Educational Science and Psychology (CESP).
