One can perform a for loop without indices over the columns of a dataframe like this: for( v in df ) ... some statements involving v ... Is there some way to do this for rows other than using indices: for( i in 1:nrow(df) ) ... some statements involving df[i,] ... If the dataframe had only numeric entries I could transpose it and then do it over columns but what about the general case?

Hi. I use winbind + squid on Debian Buster to authenticate users + authorize them based on groups they are in. It all works, well, good, but winbind's CPU utilization peaks can reach up to 100%. The same solution ran OK on Debian Jessie with up to 20% CPU utilization at most. The configuration of Buster must have been updated based on the samba version leap/shift compared to Jessie. On
