map.ctr: Map the most contributing modalities
In soc.ca: Specific Correspondence Analysis for the Social Sciences

Creates a map of the modalities contributing above average to one or more dimensions on two selected dimension.

map.ctr(
  object,
  dim = c(1, 2),
  ctr.dim = 1,
  point.shape = "variable",
  point.alpha = 0.8,
  point.fill = "whitesmoke",
  point.color = "black",
  point.size = "freq",
  label = TRUE,
  label.repel = TRUE,
  label.alpha = 0.8,
  label.color = "black",
  label.size = 4,
  label.fill = NULL,
  map.title = "ctr",
  labelx = "default",
  labely = "default",
  legend = NULL
)

`object`	a soc.ca class object as created by soc.mca and soc.csa
`dim`	the dimensions in the order they are to be plotted. The first number defines the horizontal axis and the second number defines the vertical axis.
`ctr.dim`	the dimensions of the contribution values
`point.shape`	a numerical value defining the shape of the points. If set to its default, the default scale is used. It may be mapped to a variable with a suitable length and order.
`point.alpha`	defines the alpha of the points. Values range from 0 to 1. It may be mapped to a variable with a suitable length and order.
`point.fill`	defines the fill color of the points. It may be mapped to a variable with a suitable length and order.
`point.color`	defines the color of the points. It may be mapped to a variable with a suitable length and order. See colors for some of the valid values.
`point.size`	a numerical value defining the size of the points. If set to its default, the size is determined by the frequency of each modality. It may be defined by a variable with a suitable length.
`label`	if TRUE each point is assigned its label, defined in the soc.ca object. See assign.label and add.to.label for ways to alter the labels.
`label.repel`	if TRUE overlapping labels are rearranged, see geom_text_repel or geom_label_repel.
`label.alpha`	defines the alpha of the labels. Values range from 0 to 1. It may be mapped to a variable with a suitable length and order.
`label.color`	defines the color of the labels. It may be mapped to a variable with a suitable length and order. See colors for some of the valid values.
`label.size`	defines the size of the labels. It may be mapped to a variable with a suitable length and order.
`label.fill`	defines the color of the box behind the labels. It may be mapped to a variable with a suitable length and order. This only works if label.repel is TRUE. See geom_label_repel.
`map.title`	the title of the map. If set to its default the standard title is used.
`labelx`	the label of the horizontal axis. If set to NULL a standard label is used.
`labely`	the label of the vertical axis. If set to NULL a standard label is used.
`legend`	if set to TRUE a legend is provided. Change the legend with the guides, theme and linkguide_legend functions from the ggplot2 package.
