如何使用cross将变量更改为基于其名称的因子?

(我是新来的)

members 到 factors 根据条件,如果他们的名字在列表中可用 to_factors_list

我试过用一些代码 mutate(across()) 但它会出错。

准备数据:

library(tidyverse)

# tidytuesday himalayan data
members <- read_csv("https://raw.githubusercontent.com/rfordatascience/tidytuesday/master/data/2020/2020-09-22/members.csv")

# creating list of names
to_factors_list <- members %>% 
  map_df(~(data.frame(n_distinct = n_distinct(.x))),
        .id = "var_name") %>%
  filter(n_distinct < 15) %>%
  select(var_name) %>% pull()

to_factors_list

############### output ###############
'season''sex''hired''success''solo''oxygen_used''died''death_cause''injured''injury_type'

members %>%
  mutate(across(~.x %in% to_factors_list, factor))

members %>%
  mutate_if( ~.x %in% to_factors_list, factor)
