##### Pairwise Scatter Plots showing Classification

Creates a scatter plot for each pair of variables in given data. Observations in different classes are represented by different symbols.

- Keywords
- cluster

##### Usage

```
clPairs(data, classification, symbols, colors, labels=dimnames(data)[[2]],
CEX=1, ...)
```

##### Arguments

- 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 use - 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 fu - 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.

##### Side Effects

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.
