Summarizing and aggregating your data is an excellent way to develop a deeper understanding of your data and identify areas for further analysis. In this course, Summarize and Aggregate Data in R, you'll learn how to use R. RStudio, and the dplyr package to explore your data. First, you...

I have been doing a lot of work with databases recently, some in Mathematica and some in R using the latter's very nice dplyr package.. Since I had trouble with the issue, I thought it might be worthwhile to share how to perform the equivalent of a "summarize" operation in R. The i...

In order to group our data based on multiple columns, we have to specify all grouping columns within the group_by function:data_group <- data %>% # Group data group_by(gr1, gr2) %>% dplyr::summarize(gr_sum = sum(values)) %>% as.data.frame() data_group # Print grouped data...
