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.
