My Notes

February 10, 2018
Think about the functions and workflows using in R tidyverse.
The tidyverse offers a range of functions/operations that can be organized into pipelines (workflows).

dplyr (R package)
-----
mutate
select
filter
summarize
arrange

- A function searches for input data, in the following order:
 1. text enclosed by the XML start and end tag (the function would need to be an Attribute_String)
 2. the data specified by the XML "data" attribute, which might be:
   - an XPath exression that references another node in the Xholon subtree
   - a file name
   - a URL
   - an SQL statement
   - etc.
 3. the Xholon subtree contained within its previous sibling

    dplyr is a grammar of data manipulation, providing a consistent set of verbs that help you solve the most common data manipulation challenges:
    mutate() adds new variables that are functions of existing variables
    select() picks variables based on their names.
    filter() picks cases based on their values.
    summarise() reduces multiple values down to a single summary.
    arrange() changes the ordering of the rows.
    These all combine naturally with group_by() which allows you to perform any operation “by group”.
