An R-package: Implements Partial Triadic Correspondence Analysis (PTCA)
for the analysis of data coming from "Check All That Apply" (CATA) and related designs.
So the developed acronym PTCA4CATA means:
Partial Triadic Correspondence Analysis for Check All That Apply
PTCA4CATA is a collection of functions for the analysis of Partial Triadic Correspondence Analysis: An extension of Correspondence Analysis to 3-ways data (e.g., Stimuli by Descriptors by Participants).
To install PTCA4CATA from Github use the function install_github() from the package devtools:
#install.packages("devtools") # decomment this line if devtools is not yet intalled
devtools::install_github("HerveAbdi/PTCA4CATA") # install PTCA4CATA
Note, PTCA4CATA uses other packages, to make sure that these packages are all installed,
the first time you install PTCA4CATA use this command intead:
devtools::install_github('HerveAbdi/PTCA4CATA', dependencies = TRUE)
The complete installation may take quite some time, so it could be a good time for a coffee break (or whatever else you enjoy that does not take too much time) .
