Error in residualplot_step1

[Luminphantom]

Dear hlennon! hello, when I use the function "residualplot_step1", and run follow codes:

set.seed(100) library(lcmm) model2classes <- lcmm::hlme(fixed = bmi ~ age + I(age^2), mixture= ~ age, random = ~ age, ng = 2, nwg = TRUE,
subject = "id", data = data.frame(bmi_long[1:500, ]) )

residualplot_step1(model2classes,

• nameofoutcome = "bmi",
• nameofage = "age",
• data = bmi_long,
• )

The warning in screen is: Joining, by = "id" Joining, by = c("id", "bmi") Error in aes(x = get(nameofage), y = Residuals, group = class) : 没有"aes"这个函数

and here is my R version information: R.version _
