Rename ranef to ranef.mcpfit

[JFormoso]

Hi!
I was wondering if you could help me with this. When I run this code:

model = list(
acc | trials(N) ~ 1,
1 + (1|id) ~ 0 + numerosity)

fit<- mcp(model, data = df, family = binomial())
summary(fit)
ranef(ift)

I get the following error:

Error in UseMethod("ranef") :
no applicable method for 'ranef' applied to an object of class "mcpfit"

Before that I tried using the following code with a slightly different dataset so I could use the bernoulli family:

model = list(
acc ~ 1,
1 + (1|id) ~ 0 + numerosity
)

fit<- mcp(model, data = df, family = bernoulli())
summary(fit)
ranef(ift)

I got the same error.

Thanks in advance!!

Did you load lme4 or the like after loading mcp, getting a message like "The following objects are masked from ‘package:mcp fixef ranef’"? It may be trying to use lme4::ranef() on an mcpfit object. It's a bug that mcp defines ranef instead of ranef.mcpfit so thanks for reporting!

It can be temporarily can be solved by inserting

ranef.mcpfit = mcp::ranef
ranef(fit)

(You have a typo in ranef(ift))

Yeessss!! Thank you. That was the problem (the lme4, not the typo).
