Function heuristicC [LiblineaR v2.10-8]
keywords
classif
title
Fast Heuristics For The Estimation Of the C Constant Of A Support Vector Machine.
description
heuristicC implements a heuristics proposed by Thorsten Joachims in order to make fast estimates of a convenient value for the C constant used by support vector machines. This implementation only works for linear support vector machines.
Function classCenter [iRF v2.0.0]
keywords
classif
title
Prototypes of groups.
description
Prototypes are `representative' cases of a group of data points, given the similarity matrix among the points. They are very similar to medoids. The function is named `classCenter' to avoid conflict with the function prototype in the methods package.
Function margin [iRF v2.0.0]
keywords
classif
title
Margins of randomForest Classifier
description
Compute or plot the margin of predictions from a randomForest classifier.
Function outlier [iRF v2.0.0]
keywords
classif
title
Compute outlying measures
description
Compute outlying measures based on a proximity matrix.
Function rfNews [iRF v2.0.0]
keywords
classif
title
Show the NEWS file
description
Show the NEWS file of the randomForest package.
Function roc.curve [PRROC v1.3.1]
keywords
classif
title
ROC curve
description
Computes the area under the receiver operating characteristics (ROC) curve for weighted and unweighted data. In addition to the area under the curve, the curve can be obtained by setting argument curve to TRUE.
Function pr.curve [PRROC v1.3.1]
keywords
classif
title
PR curve
description
Computes the area under the precision-recall (PR) curve for weighted and unweighted data. In contrast to other implementations, the interpolation between points of the PR curve is done by a non-linear piecewise function. In addition to the area under the curve, the curve itself can be obtained by setting argument curve to TRUE.
Function run_signalHsmm [signalHsmm v1.5]
keywords
classif
title
Predict presence of signal peptide in protein
description
Using the hidden semi-Markov model predict presence of signal peptide in eukaryotic proteins.
Function ldfactorial [phangorn v2.5.5]
keywords
classif
title
Arithmetic Operators
description
double factorial function
Function treedist [phangorn v2.5.5]
keywords
classif
title
Distances between trees
description
treedist computes different tree distance methods and RF.dist the Robinson-Foulds or symmetric distance. The Robinson-Foulds distance only depends on the toplogy of the trees. If edge weights should be considered wRF.dist calculates the weighted RF distance (Robinson & Foulds 1981). and KF.dist calculates the branch score distance (Kuhner & Felsenstein 1994). path.dist computes the path difference metric as described in Steel and Penny 1993). sprdist computes the approximate SPR distance (Oliveira Martins et al. 2008, de Oliveira Martins 2016).
