The R Journal is a peer-reviewed open-access scientific journal published by The R Foundation since 2009. It publishes research articles in statistical computing that are of interest to users of the R programming language.The journal includes a News and Notes section that supersedes the R News newsletter, which was published from 2001 to 2008.
- Statistical Computing
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. [8] 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.

Taiwan,[II][k] officially the Republic of China (ROC),[I][l] is a country[27] in East Asia.[o] It is located at the junction of the East and South China Seas in the northwestern Pacific Ocean, with the People's Republic of China (PRC) to the northwest, Japan to the northeast, and the Philippines to the south. The territories controlled by the ...

From the ideal gas law PV = nRTwe get: 1. R = P V n T {\displaystyle R={\frac {PV}{nT}}} where P is pressure, V is volume, n is number of moles of a given substance, and T is temperature. As pressure is defined as force per area of measurement, the gas equation can also be written as: 1. R = f o r c e a r e a × v o l u m e a m o u n t × t e m p e r...
The Boltzmann constant kB (alternatively k) may be used in place of the molar gas constant by working in pure particle count, N, rather than amount of substance, n, since: 1. R = N A k B , {\displaystyle R=N_{\rm {A}}k_{\rm {B}},\,} where NA is the Avogadro constant.For example, the ideal gas lawin terms of the Boltzmann constant is: 1. P V = N k B...
As of 2006, the most precise measurement of R had been obtained by measuring the speed of sound ca(P, T) in argon at the temperature T of the triple point of water at different pressures P, and extrapolating to the zero-pressure limit ca(0, T). The value of Ris then obtained from the relation: 1. c a ( 0 , T ) = γ 0 R T A r ( A r ) M u , {\displays...
The specific gas constant of a gas or a mixture of gases (Rspecific) is given by the molar gas constant divided by the molar mass (M) of the gas or mixture: 1. R s p e c i f i c = R M {\displaystyle R_{\rm {specific}}={\frac {R}{M}}} Just as the molar gas constant can be related to the Boltzmann constant, so can the specific gas constant by dividin...
The U.S. Standard Atmosphere, 1976 (USSA1976) defines the gas constant R∗as: 1. R∗ = 8.31432×103 N⋅m⋅kmol−1⋅K−1 = 8.31432 J⋅K−1⋅mol−1. Note the use of kilomoles, with the resulting factor of 1000 in the constant. The USSA1976 acknowledges that this value is not consistent with the cited values for the Avogadro constant and the Boltzmann constant. T...
Ideal gas calculator Archived 2012-07-15 at the Wayback Machine– Ideal gas calculator provides the correct information for the moles of gas involved.R, or r, is the eighteenth letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide.Its name in English is ar (pronounced / ˈ ɑːr /), plural ars, or in Ireland or / ˈ ɔːr /. The letter r is the eighth most common letter in English and the fourth-most common consonant, after t , n , and s .
Intent. The {{ r }} ( referencing) template allows to define and invoke any kind of full or shortened references (citations as well as footnotes) in articles in a very intuitive way utilizing an easy-to-remember and very short notation reducing a lot of clutter from article source code, thereby making them easier to read and maintain.
R. or r. may refer to: Reign, the period of time during which an Emperor, king, queen, etc., is ruler. Rex, abbreviated as R., the Latin word meaning King Regina, abbreviated as R., the Latin word meaning Queen Regnavit or rexit, abbreviated as r., used in historiography to designate the ruling period of a person in dynastic power, to distinguish from his or her lifespan (e.g. "Charles V (r ...
