How do you access all the column attributes associated with a column reboot instance?
The variables poisson2 ~ a matrix with 10,000 rows and 8 column attributes. Things I tried: This command only returns a vector for one of the column attributes x1_prob <- poisson2$Probability[poisson2$Reboot.Id=="Reboot 1"] The command below gave an error: all_column_attributes_for_reboot_1 <- poisson2[poisson2$Reboot.Id=="Reboot 1"] Thank you, [[alternative HTML version deleted]] ______________________________________________ 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.
