The growth of CRAN has exposed limitations of its dependency management infrastructure, particularly the fact that it assumes that dependencies always refer to the latest version of a package, meaning that new releases of CRAN packages must always be backwards compatible, [19] and that CRAN packages cannot have dependencies that are not on CRAN ...
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 ...
There are generally four classes of software used to support the Six Sigma process improvement protocol: . Analysis tools, which are used to perform statistical or process analysis;
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.
He co-authored two books based on S, S Programming and Modern Applied Statistics with S. [3] [4] Since mid-1997 he is a member of the "R Core Team" [6] and from 2000 to 2021 he was one of the most active committers to the R core. [7] The package MASS [8] is one of only fifteen "recommended packages" [9] for R (with June 2024 more than 20,900 [10]).
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]
In the analysis of data, a correlogram is a chart of correlation statistics. For example, in time series analysis , a plot of the sample autocorrelations r h {\displaystyle r_{h}\,} versus h {\displaystyle h\,} (the time lags) is an autocorrelogram .
There are a few reviews of free statistical software. There were two reviews in journals (but not peer reviewed), one by Zhu and Kuljaca [26] and another article by Grant that included mainly a brief review of R. [27] Zhu and Kuljaca outlined some useful characteristics of software, such as ease of use, having a number of statistical procedures and ability to develop new procedures.
