coef() function and Debug message

1)I tried the below function but got an error message below. could you please let me know what I did wrong with the commands?

#function:
sleep<-sleep
lm1<-lm(extra~group, sleep)
coef(lm(sleep$extra~sleep$group))

Error message:

Error in eval(predvars, data, env) :
argument "y" is missing, with no default

2)To understand the coef() function, I tried the example below provided by help. The weird thing is it was running without a problem, but after I got the error message above, when I re-ran the example again, it gave me the same error message.

x <- 1:5
coef(lm(c(1:3, 7, 6) ~ x))

Hope anybody can help me with this.

You already saved the linear model in lm1 Try coef on that

coef(lm1)
