'data' only looked for in global environment?

[rpsychologist]

Hi, it seems like the new dev version of lmerTest fails if the data is not available in the global environment? Here's an example:

data("sleepstudy", package="lme4")
test <- function() {
    tmp <- sleepstudy
    m <- lmerTest::lmer(Reaction ~ Days + (Days | Subject), data = tmp)
    summary(m)
}

# gives error
test()
## Error in checkFormulaData(formula, data, checkLHS = control$check.formula.LHS ==  : 
## bad 'data': object 'tmp' not found

# this works
tmp <- sleepstudy
test()

Is this a bug, or the expected behavior?

Hmm. Works fine for me - what is your sessionInfo?

The following object is masked from ‘package:lme4’:

lmerTest is not attached in my example, if it is it works.

The suggested code in new_lmerTest.pdf gives the same error

rm(tmp)
data("sleepstudy", package="lme4")
test <- function() {
    tmp <- sleepstudy
    m <- lme4::lmer(Reaction ~ Days + (Days | Subject), data = tmp)
    if(requireNamespace("lmerTest", quietly = TRUE)) {
        summary(lmerTest::as_lmerModLmerTest(m))
    }
}

# error
test()

Thanks.

I'll see if I can come up with a way to recover the data within as_lmerModLmerTest.

Also appears to solve issues with powerlmm and ARTool as I no longer get any errors or warnings when I check these packages with the newest lmerTest (2.0-37.90017).
