# NOT RUN {
require (datasets)
data (iris)
# Without classification
plotdata (iris [, -5]) # D<U+00E9>fault (pairs)
# With classification
plotdata (iris [, -5], iris [, 5]) # D<U+00E9>fault (pairs)
plotdata (iris [, -5], iris [, 5], type = "scatter") # Scatter plot (PCA axis)
plotdata (iris [, -5], iris [, 5], type = "boxplot") # Boxplot
plotdata (iris [, -5], iris [, 5], type = "pca") # Scatter plot (PCA axis)
plotdata (iris [, -5], iris [, 5], type = "cda") # Scatter plot (CDA axis)
plotdata (iris [, -5], iris [, 5], type = "svd") # Scatter plot (SVD axis)
plotdata (iris [, -5], iris [, 5], type = "som") # Kohonen map
# With only one variable
plotdata (iris [, 1], iris [, 5]) # D<U+00E9>fault (data vs. index)
plotdata (iris [, 1], iris [, 5], type = "scatter") # Scatter plot (data vs. index)
plotdata (iris [, 1], iris [, 5], type = "boxplot") # Boxplot
# With two variables
plotdata (iris [, 3:4], iris [, 5]) # D<U+00E9>fault (scatter plot)
plotdata (iris [, 3:4], iris [, 5], type = "scatter") # Scatter plot
