Generate scree plots

Source: R/plot_scree.R
plotScree.Rd

This function will generate a line plot of eigenvalues of PCs. These plots can be used to determine the number of factors to retain for downstream analyses (e.g GWAS).

Usage

plotScree(
  pcaObj,
  nComp = 10,
  interactive = FALSE,
  lineColor = "grey",
  pointColor = "black"
)

Arguments

pcaObj

A PCAResults object containing eigenvalue data ( e.g Eigenvalues_Datum).

nComp

Total number of principal components to plot. Defaults to 10.

interactive

Do you want to produce an interactive visualization? Defaults to FALSE.

lineColor

Color of scree line.

pointColor

Color of scree points.
