'scree_base' takes a prcomp element and diplays the percentage and the cummulative percentage of variance of variance explained by the principal components in a barplot.

scree_base(
  input_df,
  title = c("Scree plot", "Cummulative scree plot"),
  scale = FALSE,
  out_path = "none"
)

`input_df`	data frame or matrix.
`title`	vector of strings. Main titles for both plots. Default: c("Scree plot", "Cummulative scree plot")
`scale`	bool. Apply scaling when erforming PCA. Default = FALSE.
`out_path`	string. Path to save plot to png. If out_path is empty, the plot is printed to the device.

This function takes a prcomp element (i.e. an element generated by the base::prcomp function), and displays the percentage of variance and the cummulative percentage of variance explained by each principal component in a dot- and line graph.
