Map the individuals of a soc.ca analysis

Description

Creates a map of the individuals on two selected dimension.

Usage

map.ind(
  object,
  dim = c(1, 2),
  point.shape = 21,
  point.alpha = 0.8,
  point.fill = "whitesmoke",
  point.color = "black",
  point.size = 3,
  label = FALSE,
  label.repel = FALSE,
  label.alpha = 0.8,
  label.color = "black",
  label.size = 4,
  label.fill = NULL,
  map.title = "ind",
  labelx = "default",
  labely = "default",
  legend = NULL
)

Arguments

`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.
`point.shape`	a numerical value defining the shape of the points. 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. 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.

Examples

example(soc.ca)
map.ind(result)
map.ind(result, map.title = "Each individual is given its shape according to a value in a factor",
 point.shape = active[, 1], legend = TRUE)
map  <- map.ind(result, map.title = "The contribution of the individuals with new scale",
 point.color = result$ctr.ind[, 1], point.shape = 18) 
map + scale_color_continuous(low = "white", high = "red")
quad   <- create.quadrant(result)
map.ind(result, map.title = "Individuals in the space given shape and color by their quadrant",
 point.shape = quad, point.color = quad)
