In this lesson we'll take an array of objects and map it to a new array where each object is a subset of the original. We'll look at multiple ways to accomplish this, refactoring our code into a simple and easy to read function using Ramda's map, pic…

Sometimes you just need a subset of an object. In this lesson, we'll cover how you can accomplish this using Ramda's pick and omit functions, as well as the pickAll and pickBy variants of pick. const R = require('ramda'); const {pick, prop, pickBy, p…
We don't always control the data we need in our applications, and that means we often find ourselves massaging and transforming our data. In this lesson, we'll learn how to transform objects in a declarative way using ramda's evolve function. Assume…
按照某列的值拆分data.frame My data is like this (for example): ID Rate State 1 24 AL 2 35 MN 3 46 FL 4 34 AL 5 78 MN 6 99 FL I want to split the data by state and I want to get 3 data sets like below: data set 1 ID Rate State 1 24 AL 4 34 AL data set 2 ID Ra…
