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.
