19 March 2019

Use library vcd

mosaic will be used for categorical variables

#Import the file- MBAdata.csv and save as an R object mbaper
# import the file from the location-

mbaper<-read.csv("D:/1 Teaching Material/R/importfile/MBAdata.csv")

library(vcd)

## Loading required package: grid

#here the data set used is mbaper, and the variable used is Marital_status

mosaic(~mbaper$Marital_status)

mosaic(~Marital_status, data= mbaper)

# here the output will be different in terms of labeling- the block name as the labels of the variable Marital_status, and the title will be the name of the data

Adding variables

mosaic(~mbaper$Gender+mbaper$Marital_status+mbaper$Place_you_belong_to)

mosaic(~Gender+Marital_status+Place_you_belong_to, data = mbaper)

cross tab mosaic

mosaic(mbaper$Gender~mbaper$Marital_status)

adding variables

mosaic(mbaper$Gender~mbaper$Marital_status+mbaper$perceivedscorecat)

mosaic(mbaper$Gender~mbaper$Marital_status+mbaper$perceivedscorecat+mbaper$Place_you_belong_to)

mosaic(mbaper$Gender~mbaper$Marital_status)

rotating the label for better visibility

mosaic(~mbaper$Gender+mbaper$Marital_status, labeling= labeling_border(rot_labels = c(45,45,45,45)))

if there are null blocks or no observation in the combination cell, nothing will be displayed if zero_size=0

mosaic(~mbaper$Gender+mbaper$STATE, zero_size= 0)

for colouring the mosaic, wth specific colour

mosaic(~mbaper$Marital_status, gp= gpar(fill=c("red", "green")))

different types of shading based on residual

mosaic(~mbaper$Gender+mbaper$Marital_status, gp = shading_hcl)

mosaic(~mbaper$Gender+mbaper$Marital_status, gp = shading_hsv)

mosaic(~mbaper$Gender+mbaper$Marital_status, gp = shading_max)

mosaic(~mbaper$Gender+mbaper$Marital_status, gp = shading_Friendly)

mosaic(~mbaper$Gender+mbaper$Marital_status, gp = shading_Friendly2)

mosaic(~mbaper$Gender+mbaper$Marital_status, gp = shading_sieve)

mosaic(~mbaper$Gender+mbaper$Marital_status, gp = shading_binary)
