Glmer warning message to use lmer

I am trying to fit this model below:

cmod_lme4C_L <- glmer(yield ~ Location + treatment + (1|block),data=df,
                      family=gaussian(link = "identity"))

After running this code, I get warning message:

Warning message:
In glmer(yield ~ Location + treatment +  :
  calling glmer() with family=gaussian (identity link) as a shortcut to lmer() is deprecated; please call lmer() directly

Can someone please help me understand this message?

Looks like it suggests to use lmer, but I am not sure how lmer is similar to glmer in this case.

The warning is very exact in it's messaging.

When fitting a mixed-effect model with gaussian(link = "identity") it is equivalent to fitting a linear mixed effect model with normal random effects.

glmer simply changes the call to lmer(yield ~ Location + treatment + (1|block),data=df) and gives a warning.

The warning has been there for a very long time, and I would bet that it wont be deprecated in any near future, but for all intends and purposes you should use lmer(...) instead of glmer(..., family = gaussian(link = 'identity'))
