Generate scree plots — plotScree • rTASSEL

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.
