[R] lm function - strange error

[John Kane]

Tessa,

Would you please leave in the context --that is your early remarks and mine?

Most of us on the R-help list do no use nabble and it is really annoying to have to go there to see what was discussed.  I suspect that a lot of readers just don't bother and nabble users lose a lot of possible help that way.

In any case, I think your problem  is a typo in the document.  

 My first suggestion  gives  exactly the same results shown in the document you supplied.  Run this :
conc = c(0, 10, 20, 30, 40, 50)
signal = c (4, 22, 44, 60, 82, NA)
lm.r  <-  lm( signal ~ conc)
summary(lm.r)

I hope this helps.
