R Scripts for generating Graphical Plots

  • R Script to generate balloon plots, bar graphs, facetted plots etc. The script also uses a couple of functions from the data.table and dplyr packages for data munging operations.
    IntensityPlot.html
  • R Script to generate balloon plots, bar graphs, facetted plots etc. This time, using tidyverse.
    IntensityPlot-Tidy.html
  • An R Notebook with script chunks and the plots they generated ... balloon plots, bar graphs, facetted plots and circular graph.
    VariousPlots.html
See R Graphics Cookbook ( PDF Version ) for various types of graphs with code and plot examples
See http://rug.mnhn.fr/seewave/ for plotting audio files (depends on audio and tuneR pacakges for playing/recording them)

R Scripts for use with AWK's two-way IO Pipeline

The R scripts in this section are supportive scripts that are called by awk scripts. See the AWK section for examples of these. As such, these R scripts are very simple scripts; but they are indicated as executables by the hashbang line #!/usr/bin/RScript and with executable file permissions. The beauty lies in the fact that these work in tandem with awk scripts that produce the input for them dynamically.
  • R Scripts to produce basic descriptive statistics etc. These read their input from the shell (to which awk has piped its output) and returns the output back to the shell (and in turn awk). These are supportive scripts for the Two way IO pipeline awk scripts that depend upon them.

R Scripts for EEG Statistics -- EEProbe Data

  • R Script to perform statistical analysis for EEG data extracted using EEProbe from a 3-condition non-factorial design
    R_TnsAgr_Condition.html
  • R Script to perform statistical analysis for EEG data extracted using EEProbe from a 2 x 2 factorial design

  • R Script to perform statistical analysis for EEG data extracted using EEProbe from a 2 x 3 factorial design
    R_Dhesh_ND_WO_ST.html
  • R Script to perform statistical analysis of EEG data extracted using EEProbe from a 2 x 4 factorial design
    R_KurinjiD_WO_ST_CT.html
  • R Script to perform statistical analysis of EEG data extracted using EEProbe -- the main script working behind the scenes and actually calculates statistics and produces a PDF output. (Original script from the late 90s from MPI Leipzig by an unknown author; inherited, adapted and maintained by me).
