if you are making a videos please make it in details .many things are left unexplained and unclear.

Pie3D(datasetname, lables=attribute, main="variable name")

[pianissimo]

it will be great if you could explain residuals & coefficients.. little bit on how R calculates it.

[sonalisharma]

In my r studio, it is showing the invalid formula for relation <- lm(y-x), how to correct it?

#clustering plotting
ggplot(datasetname, aes(x=attributename1, y=attributename2, col=target))+geom_point()
#histogram
hist(datasetname$attribute, col="blue")
#densityplotting

plot(d)
#pie chart

variablechart
table(variablechart)
variablevalues<-c(96, 207)
variablelabls<-c(0, 1)
variablewisechart<-pie(variablevalues, variablelabls, main="attribute", col = c("red", "blue"), radius = 1)
#bar plot

bar(main="datasetname", xlab="attributename", col="blue", border="red")
#scatter plot
scatter.smooth(x=datasetname$attribute, y=datasetname$attribute, main="create variable")
#box plot
boxplot(variable_datasetname)
m=data.frame(x=1:2, y=sapply(variable_datasetname, median))
abline(lm(y~x, data=m))

[TopStudentin]

Do it for clustering, classification models etc

Your model is not working even with same number of member in variables.

Hi thank u.
Could u please tell me, how can I do regression through orgin in R

[akashmahapatra]

the x and y are of different length so lm() function is not working. what to do?
