I'm new to the R language and still struggling with compactness of R. I haven't got the right compass into the Documentation, too. So, please apologize the possibly stupidiy of my question. I have the following problem: I have two data sets combined in a data.frame x y 1.3 2.2 2.5 3.4 3.1 3.7 8.2 9.5 7.5 8.3 For the analyses of the data I want to group one column (like the classes in a histogram). So I'd like to add one column with the center of each group with width=2 for an x value in the interval of the class. So the output should look like x y x-grouped 1.3 2.2 1 2.5 3.4 3 3.1 3.7 3 8.2 9.5 9 7.5 8.3 7 What would be the R'ish idiom to do this operation?
