Filter each column of a data.frame based on a specific value

Question

Consider the following data frame:

df <- data.frame(replicate(5,sample(1:10,10,rep=TRUE)))

#   X1 X2 X3 X4 X5
#1   7  9  8  4 10
#2   2  4  9  4  9
#3            


        

Answer 1

If you only wanted to filter on the first four columns, as:

df %>% filter(X1 >= 2, X2 >= 2, X3 >= 2, X4 >= 2) 

...try this:

df %>% 
  filter_at(vars(X1:X4), #=2) )       #

An alternative is to exclude the columns you'd like to filter, as:

df %>% 
  filter_at(vars(-X5)), #=2) )
