ggplot2 is an open-source data visualization package for the statistical programming language R.Created by Hadley Wickham in 2005, ggplot2 is an implementation of Leland Wilkinson's Grammar of Graphics—a general scheme for data visualization which breaks up graphs into semantic components such as scales and layers. ggplot2 can serve as a replacement for the base graphics in R and contains a ...
The Rubik's Cube is constructed by labeling each of the 48 non-center facets with the integers 1 to 48. Each configuration of the cube can be represented as a permutation of the labels 1 to 48, depending on the position of each facet. Using this representation, the solved cube is the identity permutation which leaves the cube unchanged, while ...
A facet is a set that serves as a component-set of a cartesian product. Thus, P is called the population facet, Q is called a content facet, and the set of scores obtainable for each test is a range facet. The range facets of the various items (variables) need not be identical in size: they may have any finite number of scores, or categories ...
A faceted classification system classifies each information element along multiple explicit dimensions, facets, enabling the classifications to be accessed and ordered in multiple ways rather than in a single, predetermined, taxonomic order. [1] Facets correspond to properties of the information elements.
The earliest reference to a similar formula appears to be Armstrong (1985, p. 348), where it is called "adjusted MAPE" and is defined without the absolute values in the denominator.
The allowed facets vary based on the subject area of the classification. These facets are recorded as tables that represent recurring types of subdivisions within subject areas. There are general facets that can be used wherever appropriate, such as geographic subdivisions of the topic. Other tables are applied only to specific areas of the ...
Cutting and polishing diamonds in the Netherlands 1946. The art of cutting a gem is an exacting procedure performed on a faceting machine.The ideal product of facet cutting is a gemstone that displays a pleasing balance of internal reflections of light known as brilliance, strong and colorful dispersion which is commonly referred to as "fire", and brightly colored flashes of reflected light ...
If S is the intercept of the plane with the [1 1 0] axis, then i = 1/S. There are also ad hoc schemes (e.g. in the transmission electron microscopy literature) for indexing hexagonal lattice vectors (rather than reciprocal lattice vectors or planes) with four indices. However they do not operate by similarly adding a redundant index to the ...
