The aggregate() Function in R

[@MrNut89]

OH MY GOD!!! THANK YOU!!!! Finally I found somewhere that doesn't just write out the R code and leave it at that. I truly truly appreciate your break down and the way you show what is going on with images instead of only running lines of code.

[@1str1ker]

This was the most straightforward explanation of the aggregate function. Thank you.

who is the creator of this video and is there any official website of these courses available...? i couldn't find on there actual r lab channel

[@katedee473]

Hi there. This video was created by a team at Carleton University. Here is the link to the free, online course, with quizzes and code, etc. www.ecarleton.ca/course/view.php?id=12

Amazing. Thank you for your explanation!

[@thaisnovo208]

OBRIGADA AMIGA!!

outstanding explanation!

[@TheRealOne2294]

If I have missing data in some fields it seems like the aggregate function ignores it, how can I include the blank values for all the dates into the mean calculations?

[@vivekthaker7970]

Well put together - thanks

[@ashleygeorge3287]

Is it possible to aggregate with a different function for different variables in a data frame? For example, if I want to take the sum of the population variable but the mean of the height variable is this possible via the aggregate function? My goal is to put them all in a new data frame and trying to figure out the simplest way to do so--any assistance would be great. Thanks.

[@liangma2023]

Awesome presentation!

How would I add these aggregated values back to the data frame? I tried creating a new vector, but I got an error.

Perfect !!! Thank you

[@The_Fragile]

[@陳啟權-t7t]

Very useful, thank you!

[@bookreader1474]

Is it possible to use combination of functions e.g. mean en length at the same time?

[@saygndiler5734]

very nice!

[@josepheriksson98]

thank u so much

[@xudong5269]

amazing! WOWOW

[@gopsda]

May I know where did you get the data for heights or is that a just a dummy data? Good presentation, Thanks.

[@adityanjsg99]

Is that 'mean' the inbuilt function or user written one? .I am getting error.
