Hi, I have a data.frame which I want to aggregate. There are some grouping variables and some continuous variables for which I would like to have the mean.
However there are also some factor-variables in the data-frame that are not grouping variables and I actually would like to aggregate these variables with the unique() function. Is that possible with the standard aggregate-function? If I use it like this: aggregate(data, by=list(data$grouping1, data$grouping2), FUN=mean) I get vectors of NAs for the other factor-variables in the data.frame. But I actually want the unique value … Is that possible? thanks! ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
