Description

Find better cootrdinates for text labels GetYlim Identifies a better set of coordinates to place labels in a labeled ggplot scatterplot. #

Usage

LabeledScatterPlot(coords, ...)

## Default S3 method:
LabeledScatterPlot(coords, group = NULL,
  row.labels = NULL, col.labels = NULL, title = "", legend.title = "",
  fixed.aspect = TRUE, auto.tidy = TRUE, colors = qColors,
  auto.color = 10, general.color = "gray28", cex = 1, ...)

## S3 method for class 'smacof'
LabeledScatterPlot(object, ...)

## S3 method for class 'smacofB'
LabeledScatterPlot(object, ...)

## S3 method for class 'smacofR'
LabeledScatterPlot(object, row.description = "Rows",
  column.description = "Columns", ...)

Arguments

coords	The xy coordinates of the points.
...	Additional arguments.
group	A factor indicating group membership for each point.
row.labels	A vector of labels which will, if supplied, over-ride the rownames of coodinates.
col.labels	A vector of labels which will, if supplied, over-ride the colnames of coodinates.
title	Title for the plot.
legend.title	Title for the legend (which only appears if group is not null).
fixed.aspect	if true, forces the x and y dimensions to be on the same scale.
auto.tidy	Move the labels around so that fewer overlap.
colors	Colors that are cycled through where there is only one series, or, used to demarkate series where there are multiple series.
auto.color	When the number of rows of coords is less than or equal to this, a single color is used to label the points. Otherwise, they cycle throuogh the colors.
general.color	The color to be used in axes and titles.
cex	Relative font, line and glyph size.
object	An object to be plotted.
row.description	A title for the rows.
column.description	A title for the columns.
coords	Relative font, line and glyph size.

Value

p A ggplot plot.

Methods (by class)

• default: Default labeled scatterplot

• smacof: Labeled scatterplot of smacof object

• smacofB: Labeled scatterplot of smacofB object

• smacofR: Labeled scatterplot of smacofR object

Examples

# MDS - square
library(smacof)
data(breakfastDissimilarities)
mdsInterval <- smacofSym(breakfastDissimilarities[[4]],
    type = "interval", eps = 1e-12, itmax = 100000)
LabeledScatterPlot(mdsInterval, title = "Interval-scale MDS of Breakfast Dissimilarities")

data(colaPerceptions)
LabeledScatterPlot(colaPerceptions[,c(7,8)], title = "Scatterplot of perceptions data",
                          auto.tidy = TRUE, auto.color = 5, fixed.aspect = TRUE)
