12 mag 2024 · R has many powerful subset operators. Mastering them will allow you to easily perform complex operations on any kind of dataset. There are six different ways we can subset any kind of object, and three different subsetting operators for the different data structures. Let’s start with the workhorse of R: a simple numeric vector.

16 mag 2024 · Description. pick() provides a way to easily select a subset of columns from your data using select() semantics while inside a "data-masking" function like mutate() or summarise(). pick() returns a data frame containing the selected columns for the current group. With pick(), you typically apply a function to the full data frame.
6 giorni fa · Absorbing set. In functional analysis and related areas of mathematics an absorbing set in a vector space is a set which can be "inflated" or "scaled up" to eventually always include any given point of the vector space. Alternative terms are radial or absorbent set.
6 mag 2024 · In this vignette, we will. first introduce the concept of key in data.table, and set and use keys to perform fast binary search based subsets in i, see that we can combine key based subsets along with j and by in the exact same way as before, look at other additional useful arguments - mult and nomatch, and finally conclude by looking at the ...
10 mag 2024 · Description. The VK_KHR_portability_subset extension allows a non-conformant Vulkan implementation to be built on top of another non-Vulkan graphics API, and identifies differences between that implementation and a fully-conformant native Vulkan implementation. This extension provides Vulkan implementations with the ability to mark otherwise ...
5 giorni fa · Note. This test plugin is part of ansible-core and included in all Ansible installations. In most cases, you can use the short plugin name subset.However, we recommend you use the Fully Qualified Collection Name (FQCN) ansible.builtin.subset for easy linking to the plugin documentation and to avoid conflicting with other collections that may have the same test plugin name.
