Radar Plot Tutorial 5 Data Visualization using R , plotting performance data

how to plot radar plot to rank variables or analyse presentation using r programming and fmsb package is explained.
The radar chart is also known as web chart, spider chart, spider web chart, star chart, star plot, cobweb chart, irregular polygon, polar chart, or Kiviat diagram.
Script
#Create data
library(fmsb)
fertiliser=c("A","B","C","D","E")
crops=c("Pisum","Brinjal","Methi","Corn","Kalingad","Kharbooj","Simla","Tomato")
Fert_A=c(25,37,38,40,50,55,21,48)
Fert_B=c(45,57,32,35,22,50,32,25)
max=rep(60,8) # max for each column
min=rep(20,8) # min for each column
data=data.frame(rbind(max,min,Fert_A,Fert_B))
colnames(data)=crops
basic radar chart
radar chart color code
radarchart( data)
radar chart with grid and polygon colours
radarchart( data,pcol=c("red","blue"),cglcol="blue")
adding legend
legend(x=0.85, y=1, legend = c("Fert_A", "Fert_B"), bty = "n", pch=20 , col=c("red","blue") , text.col = "black", cex=0.9, pt.cex=1.6)
Adding Colors to webs
colors_border=c( rgb(0.2,0.5,0.5,0.9), rgb(0.8,0.2,0.5,0.9) )
colors_in=c( rgb(0.2,0.5,0.5,0.4), rgb(0.8,0.2,0.5,0.4) )
#Custom the radarChart !
radarchart( data, axistype=1,
#custom polygon
pcol=colors_border , pfcol=colors_in , plwd=4, plty=1 ,
#custom the grid
cglcol="grey", cglty=1, axislabcol="grey", caxislabels=seq(0,20,5), cglwd=1.1,
#custom labels
vlcex=0.8 )

You are the greatest teacher ever, this is the second video I have come across from you that has helped me tremendously thank you

[@DevResearch]

Glad I could help! Do watch my other videos also. It motivates me further. You made my day.

[@haimkichik]

Wow, this is neat, clean and all I need.

[@DevResearch]

Glad you like it!

What do you mean by Max and min rows in your data?. I have data of more than 150 genotypes for 15 traits. Should I add their max and min values first and then my data?.

[@DevResearch]

You need to find out max and min for each trait and use those. These are used to define scale for each trait.

Hello and thank you very much for the video. I need to stablish the minimun in zero but when I do it, R reads it as "numeric (empty). Could you tell my why this happens? Thank you!

Ensure that your data is in dataframe format, where each row is your variable. Therefore gate the dataframe using as.data.frame(rbind(max,min,value))
your data frame shall look like this
V1 V2 V3 V4 V5
max 10 10 10 10 10
min 5 5 5 5 5
value1 6 8 7 9 9
value2 5 6 8 7 6
Try following code
#radarplot
library(fmsb)
# vectors to get dataframe
max= rep(10,5)
min= rep (5,5)
value=c(6,8,7,9,9)
#get dataframe
df= as.data.frame(rbind(max,min,value1))
df
colnames(df)= c("A","B","C","D","E") # This is optional
# plot radarplot
radarchart(df)
