Summing accross individuals

[deletienne]

Dear R community,

Having performed a sentiment analysis on some papers, I got this dataframe, with sentiment scores at the sentence unit. I would like to sum these sentences to get article scores (accross element_ids).
Thank you very much in advance.

Hi!

To help us help you, could you please prepare a reproducible example (reprex) illustrating your issue? Please have a look at this guide, to see how to create one:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…

Specifically in your case take a look at group_by + summarize functions in dplyr.

Hi, thank you very much, I found by myself !
But next time I'll provide a reprex for sure.
