Explain Rattle package for R

This recipe explains what Rattle package for R

Recipe Objective

Explain the Rattle package for R.

Rattle stands for R Analytic Tool To Learn Easily. Rattle is a package written in R which provides a Graphical Data Interface (GUI) for data science, mainly for data mining. Rattle helps load a data file quickly (CSV,TXT), creates a statistical and visual summary of the data, builds different machine learning algorithms, displays the model output graphically. For installing the rattle package, use the: install.packages ("rattle") tool. This recipe demonstrates an example of what is rattle and some functions of the rattle package.

Step 1 - Install the necessary package and libraries

install.packages("RGtk2") install.packages("rattle") library(dplyr) library(rattle)

Step 2 - Define some data

sample_actual <- c(1,0,1,1,0,1,0,0,0,1) sample_predicted <- c(1,0,0,1,0,1,1,0,1,1)

Step 3 - errorMatrix() and riskchart() of rattle package

errorMatrix : It returns a matrix of true/false postive/negative values. Syntax : errorMatrix(actual,predicted) where, actual - actual values of the data predicted - predicted values of the data i.e after the model is created

errorMatrix(sample_actual,sample_predicted)

riskchart : The riskchart plots a graph between the predicted and actual data points of a binary classification model. Syntax : riskchart(actual,predicted,title) where, actual - actual values of the data predicted - predicted values of the data i.e after the model is created

riskchart(sample_actual,sample_predicted,title = 'Risk_Chart_Analysis') # plots the performance of the model {"mode":"full","isActive":false}
