[R] Removing description from lm()

[billy am]

Hi David ,

coef alone won't do as it still contains the description. As per the
example in ?coef shows ,

> x <- 1:5; coef(lm(c(1:3, 7, 6) ~ x))(Intercept)           x
       -0.7         1.5



Unless I use cat again ,

> x <- 1:5; cat(coef(lm(c(1:3, 7, 6) ~ x))[1])-0.7


Thanks!
Billy
