How to make a simple multilinear regresion model with R.

 We will use the dataset from https://drive.google.com/file/d/0BxQfpNgXuWoIWkl4M3dMZDFtUkU/view

Step 1

we call the dataset lungcap.csv

Step2

>>> file<-read.delim("C:/Users/Owner/Downloads/lungcap.csv", header=TRUE, sep = ',')

>>> attach(file)    # this appends the header variables like Age, Gender, ....

Step3

The model is below

>>> model1 <- lm(LungCap ~ Age + Height)

>>> summary(model1)

 How to train your model and test the accuracy
