Classification using support vector machine (svm) algorithm
1 2 3 4 |
featuredata |
featuredata A data frame in the featuredata format. This is a dataframe with metabolites in columns and samples in rows. Unique sample names should be provided as row names. See NormalizeMets Vignette for details. |
groupdata |
A vector with group names. |
kernel |
The kernel used. The default is the radial basis function with type C-classification. |
cost |
of constraint violation, defaults to 1. |
gamma |
parameter used for the kernel |
crossvalid |
A logical indicating whether cross-validation needs to be conducted |
k |
An integer specifying the k-fold cross-validation. Default is set to 5. |
tune |
A logical with the default set to FALSE. If TRUE, a grid search will be conducted to tune the hyperparameters, over parameter ranges supplied by the user. |
pred |
whether the predictions should be made |
pfeaturedata |
The test dataset for the predictions. The default is featuredata |
pgroupdata |
The test groupdata for the predictions. The default is groupdata |
rocplot |
A logical indicating whether a receiver operating characteristic curve needs to be plotted, along with the area under the curve (AUC) printed. |
saveoutput |
A logical indicating whether the outputs should be saved in the format
|
outputname |
The name of the output file if the output has to be saved. |
main |
Plot title. |
... |
Arguments to be passed on to other methods. |
If tune=FALSE, an object of class "svm" svm
containing the fitted model or if tune=TRUE,
an object of class tune
