Extracting columns having greater than certain values in R dataframe

Question

I have a dataframe:

Alix    Blim    Jux Gyno
0.105   0.234   0.67    0.89
0.01    0.542   0.11    0.65
0.003   0.002   0.6     0.67
0.009   0.123   0.09    0.01
         


        

Answer 1

here is a base R option with Filter

Filter(function(x) any(x > 0.6), df)
#  Jux Gyno
#1 0.67 0.89
#2 0.11 0.65
#3 0.60 0.67
#4 0.09 0.01

Or using transmute_if

library(dplyr)
df %>% 
    transmute_if(~ any(.x > 0.6), I)

Or with keep

library(purrr)
keep(df, map_lgl(df, ~ any(.x > 0.6)))
