problems subsetting
Dear all,
I have searched the forums for an answer - and there is plenty of
questions along the same line - but none of the paproaches shown worked
to my problem:
I have a data frame that I get from a csv:
summarystats<-as.data.frame(read.csv(file=f_summary));
where I have the columns Dataset, Class, Type, Category,..
Problem1: I want to find a subset of this frame, based on values in
multiple columns
What I do currently...
