Hello All: I would like to get your help on the following problem. I have the following data and the first row is the header. Spaces are not important. I want to find out distinct combinations of ATP Group and Business Event (these are the field names that you can see in the data below) that have the Category EQ (Category is the third field) and those that do not have the category EQ. In the example below, the combinations 02/A and 02/B have EQ and the combination ZM/A does not.
If I have a larger file, how to get to this answer? What did I try (with dplyr)? # I know that the below is not correct and not giving desired results file1_1 <- file1 %>% group_by(ATP.Group,Business.Event) %>% filter(Category != "EQ") %>% distinct(ATP.Group,Business.Event) # for some reason, I have to convert to data.frame to print the data correctly file1_1 <- as.data.frame(file1_1) file1_1 *Data shown below* |ATP Group|Business Event|Category| |02 |A |AC | |02 |A |AD | |02 |A |EQ | |ZM |A |AU | |ZM |A |AV | |ZM |A |AW | |02 |B |AC | |02 |B |AY | |02 |B |EQ | -- Satish Vadlamani [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
