Specify multiple input for View & Edit?

[thealk]

I may be missing something, but how do you specify multiple inputs (not arguments) for a command like "View & Edit..." that requires both a Sound and TextGrid object be selected?

Specifying 2 file paths as a list:

praat("View & Edit...", input=list(wavPath("temp.wav"), tgPath("temp.TextGrid")))

results in Error in file.exists(input) : invalid 'file' argument

Combining 2 file paths with c():

praat("View & Edit...", input=c(wavPath("temp.wav"), tgPath("temp.TextGrid")))

results in:

sh: __Edit...: command not found
Warning messages:
1: In if (!file.exists(input)) { :
  the condition has length > 1 and only the first element will be used
2: In if (output == input) { :
  the condition has length > 1 and only the first element will be used
3: In system(command = CommandStringB, intern = intern) :
  error in running command
Error: Unknown value "" for boolean "simplify".
