I am trying to select only factor columns from my data frame. Example is below:
But the code behaves strangely. Step by step:
age sex region income married children car
FALSE TRUE TRUE FALSE TRUE FALSE TRUE
save_act current_act mortgage pep ageBin
TRUE TRUE TRUE TRUE TRUE
Looks OK. Now, I assume that I just pass this matrix of TRUE/FALSE to the next step and get only the columns I need:
But as result I get all the same columns as in original bank dataframe. Nothing is filtered out. I tried it one way or another but can't find a solution. Any advice on what I am doing wrong?
