collapse::allNA identifies data.frame as list

[Steviey]

R latest, collapse latest, Ubuntu 20.04.5 LTS

df <- data.frame(A = c(1, 2, NA, 4), B = c(NA, NA, NA, NA))

result <- collapse::allNA(df)

Gives me: 
Error in collapse::allNA(df) : Unsupported type 'list' passed to allNA()

Actually I want to get a result like:
df <-df %>% dplyr::select_if(~!all(is.na(.)))

What can we do here?

Update:

Got it with:
test<-collapse::get_vars(df,!collapse::allNA)

But is the list error right?

And is there a substitute for:
df <-df %>% dplyr::mutate(across(where(is.factor),as.numeric))
?

allNA() does not have a data frame method. You can use all(dapply(df, allNA)). collapse::get_vars(df,!collapse::allNA) should not work because you are not passing a function to it. Use collapse::get_vars(df, function(x) !collapse::allNA(x)).

Okay thx, I missinterpreted 'allv(x, value)', assuming uppercase X.
Then second then seems to be:

settransform(df,get_vars(df, function(x) is.factor(x)) %>% as.numeric())
