Plot Confusion Matrix

Description

Plot a Confusion Matrix.

Usage

conf.mat.plot(pred, actual, cutoff = NULL, reference = NULL, conf.level = 0, 
              margin = 1, color = c("#ff83a8", "#83ff9b"), ...)

Arguments

pred	a vector of estimated values.
actual	a vector of actual values.
cutoff	cutoff value for the case that pred is vector of probabilites.
reference	a factor of classes to be used as the true results.
conf.level	confidence level used for the confidence rings on the odds ratios. Must be a single nonnegative number less than 1; if set to 0 (the default), confidence rings are suppressed.
margin	a numeric vector with the margins to equate. Must be one of 1 (the default), 2, or c(1, 2), which corresponds to standardizing the row, column, or both margins in each 2 by 2 table. Only used if std equals "margins".
color	a vector of length 2 specifying the colors to use for the smaller and larger diagonals of each 2 by 2 table.
...	options to be passed to fourfoldplot.
