  threshold = 0,
  reverse = NULL
)

components	A numeric vector of components to plot
sortby	Sort variables by loadings on this component (index to component vector)
threshold	Remove variables with sum(abs(loadings)) below threshold (default=0)
reverse	Vector of components that will be multiplied by -1
