Trying to understand coef column (and how to convert it to fold change)

Thanks @Kelsey_Thompson !

I am sorry to be annoying, but I still have doubts about how to do that.
That question explains how to convert the coefficient to log2fold change in case of a glm with poisson distribution. But I usually use either 'lm" or “negative binomial”. Would that be the same?

I think in case of lm, I do not need to do the following step:
fc<- exp(fit$coefficients[2]) ## Antilog coef #2

What about negative binomial?

Thanks for considering this implementation for the future.
I think it is a good idea to have it has fold change, so it is better quantifiable.
Now we have this coefficient but we do not really know how to biologically interpret it.

I thank you in advance and for your awesome work!!
