pcascree R Documentation
Scree plot of the PCA on the samples
Description
Produces a scree plot for investigating the proportion of explained variance, or
alternatively the cumulative value
Usage
pcascree(obj, type = c("pev", "cev"), pc_nr = NULL, title = NULL)
Arguments
obj
A prcomp object
type
Display absolute proportions or cumulative proportion. Possible values:
"pev" or "cev"
pc_nr
How many principal components to display max
title
Title of the plot
Value
An object created by ggplot, which can be assigned and further customized.
Examples
dds <- makeExampleDESeqDataSet_multifac(betaSD_condition = 3, betaSD_tissue = 1)
rlt <- DESeq2::rlogTransformation(dds)
pcaobj <- prcomp(t(SummarizedExperiment::assay(rlt)))
pcascree(pcaobj, type = "pev")
pcascree(pcaobj, type = "cev", title = "Cumulative explained proportion of variance - Test dataset")
