How many R libraries are there?
CRAN, the global repository of open-source packages that extend the capabiltiies of R, reached a milestone today. There are now more than 10,000 R packages available for download*. (Incidentally, that count doesn’t even include all the R packages out there.

- tidyquant.
- dygraphs.

What package is \%>\% in in R?
expm The R package, expm, defines a matrix power operator \%^\% . For an example see Matrix power in R . igraph This package defines \%–\% , \%->\% and \%<-\% to select edges. lubridate This package defines \%m+\% and \%m-\% to add and subtract months and \%–\% to define an interval.
How many R packages on github?
There are some real outliers in the data. For example, the Rcpp package, perhaps the most downloaded package of all-time, has 15.8M downloads and only 377 stars….Analyzing the Data.

What is base R package?
base-package: The R Base Package This package contains the basic functions which let R function as a language: arithmetic, input/output, basic programming support, etc. Its contents are available through inheritance from any environment. For a complete list of functions, use library(help = “base”) .
Are packages libraries?
Packages are collections of R functions, data, and compiled code in a well-defined format. The directory where packages are stored is called the library.
What does library () do in R?
library(help = somename) computes basic information about the package somename, and returns this in an object of class “packageInfo” . (The structure of this class may change in future versions.) When used with the default value ( NULL ) for lib. loc , the attached packages are searched before the libraries.
Can R packages have viruses?
RStudio does not certify or verify that R or R packages are free from vulnerabilities. One of the most common questions we’ve gotten while talking to admins about R packages is whether or not RStudio Products include virus scanners. The answer is no.
What is the Cran repository?
The Comprehensive R Archive Network (CRAN) is the main repository for R packages. The main advantage to getting your package on CRAN is that it will be easier for users to install (with install. packages ). Your package will also be tested daily on multiple systems.
What is the best library for data visualization in R?
Ggplot2 is the one of the best library for data visualization in R. The ggplot2 library implements a “grammar of graphics” (Wilkinson, 2005). This approach gives us a coherent way to produce visualizations by expressing relationships between the attributes of data and their graphical representation.
What is the best package for are database?
RMySQL, RPostgresSQL, RSQLite – If you’d like to read in data from a database, these packages are a good place to start. Choose the package that fits your type of database. XLConnect, xlsx – These packages help you read and write Micorsoft Excel files from R.
What is the use of date library in R?
This library serves its purpose really well. It’s mainly used for data wrangling. It makes the dealing of date-time easier in R. You can do everything you ever wanted to do with date arithmetic using this library, although understanding & using available functionality can be somewhat complex here.
What tools do you use to test your your packages?
devtools – An essential suite of tools for turning your code into an R package. testthat – testthat provides an easy way to write unit tests for your code projects. roxygen2 – A quick way to document your R packages. roxygen2 turns inline code comments into documentation pages and builds a package namespace.
