correlationPlotter

Description

Computes and plots a correlation circle (used in multivariate analyses). Correlation is computed between measured items and components (factors, dimensions, principal axes, etc...).

Usage

correlationPlotter(
  data_matrix,
  factor_scores,
  x_axis = 1,
  y_axis = 2,
  col = NULL,
  pch = NULL,
  xlab = "",
  ylab = "",
  main = "",
  axis.lwd = 3,
  circle.lwd = 3,
  circle.col = "#00000040",
  asp = 1,
  dev.new = TRUE
)

Arguments

`data_matrix`	A set of data (i.e., original measures and observations)
`factor_scores`	One set of factor scores that were computed from the original data matrix.
`x_axis`	Which axis is the x-axis? Default is 1.
`y_axis`	Which axis is the y-axis? Default is 2.
`col`	A single-column matrix of colors for each data point.
`pch`	A single-column matrix of pch for each data point. Indicates which point style to use for each item. See `par`.
`xlab`	A label to be placed along the x-axis.
`ylab`	A label to be placed along the y-axis.
`main`	A title to be placed at the top of the graph.
`axis.lwd`	numeric. Line width for the axes.
`circle.lwd`	numeric. Line width for the circle.
`circle.col`	color for the circle
`asp`	numeric. Aspect ratio (see `asp` in `par`).
`dev.new`	boolean. If TRUE, `dev.new` is called internally to create new device. If FALSE, a device must already be open.
