[R] A question on the abline function

[PIKAL Petr]

Hi

you did not provide enough info for resolving your error (at least not enough for myself).

How did you call abline?

Standard way of calling abline is:

fit <- lm(...)
abline(fit) 

So please provide code you used, R version maybe OS and probably some data to play with.

Regards
Petr
