clPairs {mclust} | R Documentation |
Creates a scatter plot for each pair of variables in given data. Observations in different classes are represented by different symbols.
clPairs(data, classification, symbols, colors, labels=dimnames(data)[[2]], CEX=1, ...)
data |
A numeric vector, matrix, or data frame of observations. Categorical variables are not allowed. If a matrix or data frame, rows correspond to observations and columns correspond to variables. |
classification |
A numeric or character vector representing a classification of observations
(rows) of data .
|
symbols |
Either an integer or character vector assigning a plotting symbol to each
unique class in classification . Elements in symbols
correspond to classes in order of appearance in the sequence of
observations (the order used by the function unique ).
The default is given is .Mclust\$classPlotSymbols .
|
colors |
Either an integer or character vector assigning a color to each
unique class in classification . Elements in colors
correspond to classes in order of appearance in the sequence of
observations (the order used by the function unique ).
The default is given is .Mclust\$classPlotColors .
|
labels |
A vector of character strings for labeling the variables. The default
is to use the column dimension names of data .
|
CEX |
An argument specifying the size of the plotting symbols. The default value is 1. |
... |
Additional arguments to be passed to the graphics device. |
Scatter plots for each combination of variables in data
are
created on the current graphics device. Observations of different
classifications are labeled with different symbols.
