classError {mclust} | R Documentation |
Error for a given classification relative to a known truth. Location of errors in a given classification relative to a known truth.
classError(classification, truth)
classification |
A numeric or character vector of class labels. |
truth |
A numeric or character vector of class labels.
Must have the same length as
classification .
|
classErrors
will only return one possibility
if more than one mapping between classification and truth results in the
minimum error.
classError
gives the fraction of elements
misclassified for classification
relative to truth
.
classErrors
is a logical vector of the
same length as classification
and
truth
which gives the location
of misclassified elements in classification
relative to truth
.
