Help with simplifying table and finding total amount of parameters per date.

[Marench]

Hi! I'm fairly new to R, and am having some troubles finding the right packages etc. for what I want to do.
As you can see in the table, I have several parameters which have numeric values for certain dates. So what I want to do, is finding the total amount of ad.m, total amount of ad.f etc. for each date - so I eventually can make a graph. So instead of having the values over several rows, I only want one value for each parameter for every date. Does this make sense?

Thank you in advance for your help!

Hi,
You should take a look at (Dyplr)[https://dplyr.tidyverse.org/] that will be very useful for data manipulation in R, and will do what you need out of the box.

Here is a nice free book that will teach you the basics of data wrangling using the tidyverse family of tools
