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? ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
