I have a df in R
sample1 sample2 sample3 sample4
price1 10 21 32 43
price2 12 24 15 18
price3 1 2 15 8
price4 16 30 44 58
price5 18 33 48 63
price6 20 36 52 68
price7 22 39 56 73
price8 24 42 60 78
price9 26 45 64 83
price10 28 48 68 88
I would like to perform an operations where i would like to drop rows that have values less than 15 in more than 2 columns
so
price3 1 2 15 8
would be deleted
We can use rowSums
to create the logical vector
df1[rowSums(df1 < 15) <=2 , , drop = FALSE]
# sample1 sample2 sample3 sample4
#price1 10 21 32 43
#price2 12 24 15 18
#price4 16 30 44 58
#price5 18 33 48 63
#price6 20 36 52 68
#price7 22 39 56 73
#price8 24 42 60 78
#price9 26 45 64 83
#price10 28 48 68 88
