The PCADSC methods are described in our article manuscript.
The basic functionality of the package can be inspected using the following lines of code:
library(PCADSC) #Load iris data data(iris) #Define grouping variable, grouping the observations by whether their species is #Setosa or not iris$group <- "setosa" iris$group[iris$Species != "setosa"] <- "non-setosa" #Make a PCADSC object, splitting the data by "group" irisPCADSC <-PCADSC(iris, "group", var=setdiff(names(iris), c("group", "Species")), doCE = TRUE, doAngle = TRUE, doChroma = TRUE) #Make a cumulative eigenvalue (CE) plot CEPlot(irisPCADSC) #Make an angle plot anglePlot(irisPCADSC) #Make a chroma plot chromaPlot(irisPCADSC)
Our current to-do list for the package is posted below. If you have any further suggestions for added functionality, or have a bug to report, please open an issue and let us know.
