Add columns in R based on condition 3 -

-

the issue add new column dataframe when condition fulfilled. when first columns 1 1 "hom" , when 0 1 "het" should outputted. appreciate help.

example:

1  1  -->  hom 1  1  -->  hom 0  1  -->  het  1  1  -->  hom 0  1  -->  het

if these 2 conditions check , checking first column of dataframe sufficient

df <- data.frame(num1 = c(1,0,1), num2 = c(1,1,1)) ifelse(df$num1 == 1,"hom","het") # [1] "hom" "het" "hom"
