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

We could use colSums to subset columns using base R

df[colSums(df > 0.6) > 0]

# Jux Gyno
#1 0.67 0.89
#2 0.11 0.65
#3 0.60 0.67
#4 0.09 0.01

Or with dplyr, select_if

library(dplyr)
df %>% select_if(~any(. > 0.6))
