Finally, to choose different measures of performance, additional arguments are given to trainControl.The summaryFunction argument is used to pass in a function that takes the observed and predicted values and estimate some measure of performance. Solved: The report looks well on Power BI desktop, using my R installation. The caret R package was designed to make finding optimal parameters for an algorithm very easy. Open R console and install it by typing: 1. install.packages("caret") caret package provides us direct access to various functions for training our model with various machine learning algorithms like Knn, SVM, decision tree, linear regression, etc. 15, Mar 22. If you prefer to get separate statistics for various time intervals in your time series, use stat.slide(). read.csv is the base function. The arguments to the function should be the same as those in defaultSummary. In order to use the function, we have to install and load the dplyr package: install.packages("dplyr") # Install & load dplyr package library ("dplyr") Now, let's run exactly the same code as before: sample_n ( data.frame(1:10), 2) # Applying sample_n function # X1.10 # 1 7 # 2 1.

The first argument to cost should correspond to the observed responses and the second argument should correspond to the predicted or fitted responses from the generalized linear model. 1. naiveBayes(formula, data, laplace = 0, subset, na.action = na.pass) The formula is traditional Y~X1+X2++Xn. This should make 5 folds and I can use them in index argument of trainControl function: myControl <- trainControl ( method = "cv", number = 5, summaryFunction = twoClassSummary, classProbs = TRUE, index = myFolds ) From documentation: index a list with elements for each resampling iteration. This can be a name of the function or the function itself. 11049, 05422-970 So Paulo, Brazil 2 Instituto de Matemtica e.
