Hello, I am new to the Powerlmm package and haven't used R for a while. I have tried to update all relevant packages. But when I tested the Powerlmm package with the example provided online, it kept giving me this error message Error in prettyNum(.Internal(format(x, trim, digits, nsmall, width, 3L, : invalid value 0 for 'digits' argument

Here was what I tested:

library(powerlmm)

p <- study_parameters(n1 = 11,

  • n2 = 20,
  • icc_pre_subject = 0.5,
  • var_ratio = 0) get_power(p)

Any feedback or guidance would be much appreciated!
