Hello, Please, I want to know how the functional data are defined in programming code R. If possible an illustrative example of code can help me to understand better. Yours sincerely. [[alternative HTML version deleted]]

Good Morning, I am doing some research to develop a new course where I teach. I am looking for a book to use in the course content to teach accomplishing SQL in R. Does anyone know of a book on this topic to recommend for consideration? Thank You, -- *Stephen Dawson, DSL* /Executive Strategy Consultant/ Business & Technology +1 (865) 804-3454 http://www.shdawson.com

I think a simple reproducible example ("reprex") may be necessary for you to get a useful reply. Questions with vague specifications such as yours often result in going round and round with attempts to clarify what you mean without a satisfactory answer. Clarification at the outset with a reprex may save you and others a lot of frustration. Cheers, Bert On Sat, Nov 4, 2023 at 1:41?AM

Hi, I'd like to graph three lines on ggplot2 and I intend the lines to be "solid", "dashed", and "dotted". The legend names are "name_b", "name_a", "name_c". I'd like to legend to present in the order: the "name_b" at the top, and "name_c" at the bottom. As a consequence, the legend is indeed in the order:

Hello Ulrik, Can you please explain this code means how and what this code is doing because I'm not able to understand it, if you can explain it i can use it in future by doing some Lil bit manipulation. Thanks data_help <- data_help %>% mutate(Purchase_ID = 1:n()) %>% group_by(Purchase_ID) %>% do(split_items(.)) cat_help %>% gather("Foo",

Hi Jeff, Thank you for the suggestions -- I appreciate your help. Unfortunately, the result2 has two problems... (1) there are now 3 date columns (it looks like 2 cols are merged into 1 col) (2) the output rows should not have any of the basistime dates repeated (maybe I misstated the problem); I need the max fcst value by basistime, but also list the date value for that row; for example:
