Generate scree plots

Description

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.
