classification: classification

In elpidiofilho/easyFit: Routines for fit classification and regression models in easy way

Description

This function performs the training of the chosen classifier

Usage

classification(df.train, formula = NULL, preprocess = NULL,
  classifier = "rf", nfolds = 10, repeats = 1, index = NULL,
  cpu_cores = 4, tune_length = 5, metric = "Kappa", seeds = NULL,
  verbose = FALSE)

Arguments

df.train	Training dataframe
formula	A formula of the form y ~ x1 + x2 + ... If users don't inform formula, the first column will be used as Y values and the others columns with x1,x2....xn
preprocess	pre process
classifier	Choice of classifier to be used to train model. Uses algortims names from Caret package.
nfolds	Number of folds to be build in crossvalidation
repeats	repeats
index	index
cpu_cores	Number of CPU cores to be used in parallel processing
tune_length	This argument is the number of levels for each tuning parameters that should be generated by train
metric	metric used to evaluate model fit. For numeric outcome ("RMSE", "Rsquared)
seeds	seeds seeds
verbose	verbose
