if_any inside mutate, unexpected return on single columns

[mp8]

I am not sure if this will be use case for any, but trying to use if_any directly inside mutate changes behavior unexpectedly when only single column is in the .cols with nothing specified for .fns. Apologies if this was already documented:

library(dplyr)

# Sample data
zdata <- tibble(
    id = 1:5,
    col_a = c(10, 25, 5, 30, 15),
    col_b = c(20, 12, 8, 40, 22),
    col_c = c(5, 18, 10, 15, 7)
)

#Trying to use if_any directly inside mutate, expected logical output
#Case1
zdata %>% mutate(any_big = if_any(c(col_a,col_b,col_c), ~ .x>10))  #Returns logical

#Case2
zdata %>% mutate(any_big = if_any(c(col_a,col_b,col_c)))                #Returns logical

#Case3
zdata %>% mutate(any_big = if_any(c(col_a), ~ .x>10))                   #Returns logical

#Case4
zdata %>% mutate(any_big = if_any(c(col_a)))                       #Does not return logical output, returns column as it is..

# A tibble: 5 × 5
     id col_a col_b col_c any_big
  <int> <dbl> <dbl> <dbl>   <dbl>
1     1    10    20     5      10
2     2    25    12    18      25
3     3     5     8    10       5
4     4    30    40    15      30
5     5    15    22     7      15

That does look like a bug! I think the y here should actually be a vector of TRUE or FALSE depending on the op involved

I think this is highly related to #7077
