Just starting on my journey to learn R and the book I am using is "Using R for Introductory Statistics"
One of the problems (page 15, 1.10) goes as follows: The monthly sales fig for 2002 were (2700, 2600, 3050, . . ). Using diff() find the month with greatest increase from prev month. I created a msales var: msales = c(2700, 2600, 3050 . . ) I named them: names(msales)=c("Jan", Feb", "Mar" . . .) to find the month with greatest increase from prev month: max(diff(msales)) I get the numeric value displayed when I execute the above function, but not the month. cumsum(msales) displays the results under each month, but not max. How can I get both the month and value displayed? Thanks -Sudhakar ps: no, I am not a student seeking answers to exercises :) [[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.
