Combine the results of several "InstEvaL" course evaluations and plot them

The R package instevalR and the app Shiny InstevalR are useful for people doing course evaluations (at universities, e.g., U Mannheim) with the software InstEvaL. The package has functions to combine the results of several course evaluations (e.g., different courses/cohorts of a single instructor) and to plot those results:

In order to use this package, you need three things:

1. The CSV-files with the raw data of your course evaluations, which you can download from InstEvaL (log in to InstEvaL -> Results -> Raw data). Please save all your CSV-files in a single directory (they probably have names ending with 'evaluationen.csv').
2. R, which you can download from https://www.r-project.org
3. The package instevalR

The easiest way to install the package instevalR is to install it directly from GitHub:

install.packages("devtools")
devtools::install_github("hplieninger/instevalR")

After you have your CSV-files, R, and the package, you can get started:

library("instevalR")                             # load in every new R session
tmp1 <- read_eval()                              # read raw data
dat1 <- join_eval(tmp1)                          # combine into single data frame
plot_eval(dat1)                                  # plot
?plot_eval                                       # help; check out Examples

If you're unfamiliar with R, you may find the shiny app useful which you can run locally using shiny_eval() or simply go to https://hplieninger.shinyapps.io/ShinyInstevalR/. Furthermore, you can simulate data using sim_eval(), and you can create a nice summary table using datatable_eval().

library("instevalR")                             # load in every new R session
shiny_eval()                                     # interactive shiny app

dat1 <- sim_eval()                               # simulate data   
plot_eval(dat1)                                  # plot
datatable_eval(dat1)

Happy teaching. You are welcome to send any bug reports, feature requests, or comments via GitHub Issues or via email.
