ExpParcoord {SmartEDA}

Parallel Co ordinate plots

Description

This function creates parallel Co ordinate plots

Usage

ExpParcoord(
  data,
  Group = NULL,
  Stsize = NULL,
  Nvar = NULL,
  Cvar = NULL,
  scale = NULL
)

Arguments

data

Input dataframe or data.table

Group

stratification variables

Stsize

vector of startum sample sizes

Nvar

vector of numerice variables, default it will consider all the numeric variable from data

Cvar

vector of categorical variables, default it will consider all the categorical variable

scale

scale the variables in the parallel coordinate plot (Default normailized with minimum of the variable is zero and maximum of the variable is one) (see ggparcoord details for more scale options)

Details

The Parallel Co ordinate plots having the functionalities of visulization for sample rows if data size large. Also data can be stratified basis of Target or group variables. It will normalize all numeric variables between 0 and 1 also having other standardization options. It will automatically make dummy (1,0) variables for categorical variables

Value

Parallel Co ordinate plots

Examples

CData = ISLR::Carseats
# Defualt ExpParcoord funciton
ExpParcoord(CData,Group=NULL,Stsize=NULL,
			   Nvar=c("Price","Income","Advertising","Population","Age","Education"))
# With Stratified rows and selected columns only
ExpParcoord(CData,Group="ShelveLoc",Stsize=c(10,15,20),
			   Nvar=c("Price","Income"),Cvar=c("Urban","US"))
# Without stratification
ExpParcoord(CData,Group="ShelveLoc",Nvar=c("Price","Income"),
			   Cvar=c("Urban","US"),scale=NULL)
# Scale changed std: univariately, subtract mean and divide by standard deviation
ExpParcoord(CData,Group="US",Nvar=c("Price","Income"),
			   Cvar=c("ShelveLoc"),scale="std")
# Selected numeric variables
ExpParcoord(CData,Group="ShelveLoc",Stsize=c(10,15,20),
			   Nvar=c("Price","Income","Advertising","Population","Age","Education"))
