Partial fail in new Box-Cox-handling in insight 0.99.0.15

[strengejacke]

Fixes #970

[JoakimStefansson]

Should this be available in insight 0.99.0.16?

[strengejacke]

Yes

[JoakimStefansson]

It doesn't seem to be. Should I open a new issue?

[strengejacke]

Works for me:

library(insight)
packageVersion("insight") # ‘0.99.0.15’
#> [1] '0.99.0.16'

a <- aov(formula = (mpg ^ 1.3 - 1) / 1.3 ~ hp, data = mtcars)
insight::find_transformation(a) # "box-cox" - correct
#> [1] "box-cox"
insight::get_transformation(a) # also has a correct output
#> $transformation
#> function(x) (x^1.3-1) / 1.3
#> <environment: 0x000001af044791c0>
#> 
#> $inverse
#> function(x) exp(log(1 + 1.3 * x) / 1.3)
#> <environment: 0x000001af044791c0>

a <- aov(formula = (mpg ^ -1.3 - 1) / -1.3 ~ hp, data = mtcars)
insight::find_transformation(a)
#> [1] "box-cox"
insight::get_transformation(a)
#> $transformation
#> function(x) (x^-1.3-1) / -1.3
#> <environment: 0x000001af068b0778>
#> 
#> $inverse
#> function(x) exp(log(1 + -1.3 * x) / -1.3)
#> <environment: 0x000001af068b0778>

Try easystats::install_latest(force = TRUE) to update to most recent package versions.

[JoakimStefansson]

Yes, after the forced update, it also works for me.
I had updated to insight 0.99.0.16 with easystats::install_latest(source="development").

[strengejacke]

source="development", that's the default, you don't need to specify that. But sometimes, if we forget to increase version numbers in a PR, easystats::install_latest() won't install newer versions, because version numbers were the same. force = TRUE always installs from r-universe and does not check version numbers.
