Hi Team,
I can write a for loop like this:
for (i in columns(df)){

But it will working on all column in dataframe df. If I want to work on some of specific fields (say: the fields' name content 'date'), how should I modify the for loop? I changed the code below, but it doesn't work.
for (i in columns(df) %in% 'date' ){

Thank you,
