error from explain

[billnjcn111]

Hi,
I got some nasty errors and hopefully authors can check into this.
something odd here: no error in model but in the explain step:
model.src <- randomForestSRC::rfsrc(Surv(OS, status) ~ ., data = data)
explain(model.src)
Error in grep("NODE", lns):(length(lns) - 2) : argument of length 0
In addition: Warning messages:
1: In if (substring(pattern, 1, 4) == "@rm_") { :
the condition has length > 1 and only the first element will be used
2: In if (substring(pattern, 1, 1) == "@") { :
the condition has length > 1 and only the first element will be used

Hello, I'm going to check on this, but can't seem to replicate your code. Can you include a reproducible example using reprex::reprex(..., session_info = TRUE).

Sorry for the misunderstanding. To debug this error I would need the output of

reprex::reprex({
# the code that causes
# the error goes here

} , session_info = TRUE)

Closing this because of no info. Feel free to reopen with additional output.
