[R] undesirable output for lm( )

[Swapnil Khobragade]

Hi,

I have written this code and it is working fine

Example 1:

>fit <- lm(cpi ~ year + quarter)
>(cpi2011 <- fit$coefficients[[1]] + fit$coefficients[[2]]*2011 + fit$coefficients[[3]]*(1:4))

*****************************************************************************************
Example 2:

>fit <- lm(cpi ~ year )
>(cpi2011 <- fit$coefficients[[1]] + fit$coefficients[[2]]*2011)

I'm getting an undesirable output for this calculation.
Plz help in correcting the mistakes to get clear output.
