QPress
This package simulates qualitative press perturbation scenarios for network models specified as signed directed graphs.
The package has four main functions.
-
The package reads signed directed graphs from pre-specified formats and generates a community matrix.
-
The package samples a community matrix to generate a set of outcomes which can explored interactively.
-
The package provides a means to specify combinations of validation criteria and press perturbation scenarios, and to determine the proportion of simulated outcomes that meet these specifications.
Installing
First install the dependencies from CRAN:
install.packages(c("tcltk2","XML","devtools"))
(This assumes that R has been compiled with Tcl/Tk support, which should be true for most distributions.)
Then install QPress itself from GitHub, using the devtools package.
devtools::install_github("SWotherspoon/QPress")
(QPress otherwise does not need devtools for normal use.)
