i have created a polynomial regression model to predict some values for a variable which have 500 rows : ## Heading ##
there are around 500 values "planned"  and on the basis of this i have to predict new values  which "actual". kindly help me with the coding , 
here i'm showing that how i am doing it manually   

`predict(poly_reg, data.frame(planned= 48.80000,
                             Level2 = 48.80000^2,
                             Level3 = 48.80000^3))`
