dplyr is an R package whose set of functions are designed to enable dataframe (a spreadsheet-like data structure) manipulation in an intuitive, user-friendly way. It is one of the core packages of the popular tidyverse set of packages in the R programming language. [1]
R is a programming language for statistical computing and data visualization. It has been adopted in the fields of data mining, bioinformatics and data analysis. [9] The core R language is augmented by a large number of extension packages, containing reusable code, documentation, and sample data. R software is open-source and free software.
However, if data is a DataFrame, then data['a'] returns all values in the column(s) named a. To avoid this ambiguity, Pandas supports the syntax data.loc['a'] as an alternative way to filter using the index. Pandas also supports the syntax data.iloc[n], which always takes an integer n and returns the nth value, counting from 0. This allows a ...
Frame (artificial intelligence), machine-usable formalizations of concepts or schemata that can be used for knowledge representation; Frame (networking), a data transmission unit or network packet that includes frame synchronization information; Distribution frame, in telecommunications; Mainframe computer; Page frame, an available chunk of memory

The tangent frame bundle (or simply the frame bundle) of a smooth manifold is the frame bundle associated with the tangent bundle of . The frame bundle of M {\displaystyle M} is often denoted F M {\displaystyle FM} or G L ( M ) {\displaystyle \mathrm {GL} (M)} rather than F ( T M ) {\displaystyle F(TM)} .
The data link layer is concerned with local delivery of frames between nodes on the same level of the network. Data-link frames, as these protocol data units are called, do not cross the boundaries of a local area network. Inter-network routing and global addressing are higher-layer functions, allowing data-link protocols to focus on local ...
