This website is made to share the assignments I worked out for statistic courses in the Epidemiology Graduate Program of the Julius Center, Utrecht, the Netherlands
pre-testing and type-I error rates: re-analysis of Rasch
the circle dance: strategy for positioning at equidistance in a group
working directory
Due to how this website was made, the R-code ‘thinks’ it is in the analysis
subdirectory, while the data sits in the data
directory, which is found from the parent directory. Working with Rmarkdown and keeping track of the directory is not too easy at all. After modern methods, I switched to using the package here
, which is specifically designed to target such problems.
Before that I used the function fromParentDir
, which allows you to call files from the parent directory. The function can be found in the package epistats
, which can be installed with devtools::install_github("vanAmsterdam/epistats")
If devtools
is not yet installed, first run install.packages("devtools")
packages and functions
Sometimes different packages provide functions with the same names. To make sure you use the intended function (and to circumvent using library(package)
), use <package>::<function>
to use <function>
from package <package>
, like epistats::fromParentdir
