However, similar biases can occur when your linear model is missing important predictors, polynomial terms, and interaction terms. Statisticians call this specification bias, and it is caused by an underspecified model.

creating a vector:
c(1, 2,3)
this is a vecotr include 1,2,3
c('a','b')
this is a vector includes a and b
seq(5,9)
creates sequence of data from 5 to 9
5:9
is like the above code
seq( 5, 9, 0.5) create a vector from 5 to 9 with .5 interval
