confusionMatrix

plotConfMat

Generate a confusion matrix for Random Forest classification 
 models with error rates translated into percent correctly classified, 
 and columns for confidence intervals added.

Estimate significance of importance metrics
for a Random Forest model by permuting the response
variable. Produces null distribution of importance
metrics for each predictor variable and p-value of
observed. Provides summary and visualization functions for 'randomForest'
results.

confusionMatrix function

<dl><dt>x</dt>
<dd>a <code>rfPermute</code> or <code>randomForest</code> model object.</dd>
<dt>conf.level</dt>
<dd>confidence level for the <code><a href="/link/binom.test?package=rfPermute&version=2.5.2" data-mini-rdoc="rfPermute::binom.test">binom.test</a></code> 
confidence interval</dd>
<dt>threshold</dt>
<dd>threshold to test observed classification 
probability against. Should be a number between 0 and 1. 
If not <code>NULL</code>, the output matrix will have extra 
columns giving the one-tailed probability that the true correct 
classification is &gt;= <code>threshold</code>.</dd>
