invalid value 0 for 'digits' argument
but I am not using the prettyNum function
I do not Know where is the problem
any one can help to me

Hi!

To help us help you, could you please prepare a reproducible example (reprex) illustrating your issue? Please have a look at this guide, to see how to create one:

I am using edf files dataset
pdf library
png library
generate_eeg_waveforms <- function(mode = "seizure",
which.expert = NA,
annotations.file = NA,
patient.IDs,
window,
down.sampling.factor = 4,
non.seizures.chunks = 10,
preprocessing = FALSE,
random = TRUE,
format = "png", # or pdf
save.to.file = FALSE,
dir) {

}

and the error was Error in prettyNum(.Internal(format(x, trim, digits, nsmall, width, 3L, :
invalid value 0 for 'digits' argument

You are showing a mere function definition with no body ? This makes no sense in relation to your opening statements.

sorry, What I should to do
I deleted the bracket but I got same error
generate_eeg_waveforms(

  • mode = "seizure",
  • which.expert = we[1],
  • annotations.file = ann.f[1],
  • patient.IDs = p.ID,
  • window = 10,
  • down.sampling.factor = 4,
  • non.seizures.chunks = 10,
  • preprocessing = FALSE,
  • random = FALSE,
  • format = "png",
  • save.to.file = TRUE,
  • dir = dir
  • )
    Error in prettyNum(.Internal(format(x, trim, digits, nsmall, width, 3L, :
    invalid value 0 for 'digits' argument

I have no knowledge of this function or how it should work. What package is it from ?
