fs

cran
99th

Percentile

A cross-platform interface to file system operations, built on top of the 'libuv' C library.

memoise

cran
99th

Percentile

Cache the results of a function so that when you call it again with the same arguments it returns the pre-computed value.

covr

cran
98th

Percentile

Track and report code coverage for your package and (optionally) upload the results to a coverage service like 'Codecov' <http://codecov.io> or 'Coveralls' <http://coveralls.io>. Code coverage is a measure of the amount of code being exercised by a set of tests. It is an indirect measure of test quality and completeness. This package is compatible with any testing methodology or framework and tracks coverage of both R code and compiled C/C++/FORTRAN code.

lintr

cran
96th

Percentile

Checks adherence to a given style, syntax errors and possible semantic issues. Supports on the fly checking of R code edited with 'RStudio IDE', 'Emacs', 'Vim', 'Sublime Text' and 'Atom'.

gmailr

cran
95th

Percentile

An interface to the Gmail RESTful API. Allows access to your Gmail messages, threads, drafts and labels.

87th

Percentile

A framework to create Bootstrap <http://getbootstrap.com/> HTML reports from 'knitr' 'rmarkdown'.

bench

cran
80th

Percentile

Tools to accurately benchmark and analyze execution times for R expressions.

types

cran
57th

Percentile

Provides a simple type annotation for R that is usable in scripts, in the R console and in packages. It is intended as a convention to allow other packages to use the type information to provide error checking, automatic documentation or optimizations.

primerTree

cran
47th

Percentile

Identifies potential target sequences for a given set of primers and generates taxonomically annotated phylogenetic trees with the predicted amplification products.

available

cran
18th

Percentile

Check if a given package name is available to use. It checks the name's validity. Checks if it is used on 'GitHub', 'CRAN' and 'Bioconductor'. Checks for unintended meanings by querying Urban Dictionary, 'Wiktionary' and Wikipedia.

glue

cran
18th

Percentile

An implementation of interpreted string literals, inspired by Python's Literal String Interpolation <https://www.python.org/dev/peps/pep-0498/> and Docstrings <https://www.python.org/dev/peps/pep-0257/> and Julia's Triple-Quoted String Literals <https://docs.julialang.org/en/stable/manual/strings/#triple-quoted-string-literals>.

autoinst

github
18th

Percentile

Automatically install packages when they are missing.

fstrings

github
18th

Percentile

An implementation of Interpreted String Literals (f-strings) for R.

lookup

github
18th

Percentile

Provides a simple interface to lookup and print R function definitions, including C and C++ compiled code from .Call, .C, .Internal and .External calls. Also lookup of S3 and S4 generics, including a simple dialog to print any or all of the loaded methods for the generic.

rex

cran
18th

Percentile

A friendly interface for the construction of regular expressions.

withr

cran
18th

Percentile

A set of functions to run code 'with' safely and temporarily modified global state. Many of these functions were originally a part of the 'devtools' package, this provides a simple package with limited dependencies to provide access to these functions.

roomba

github
18th

Percentile

This is a package to transform large, multi-nested lists into a more user-friendly format. The initial focus is on making processing of return values from `jsonlite::fromJSON()` queries more seamless, but ideally this package should be useful for deeply-nested lists from an array of sources.

knitr

cran
99.5th

Percentile

Provides a general-purpose tool for dynamic report generation in R using Literate Programming techniques.

markdown

cran
99.5th

Percentile

Provides R bindings to the 'Sundown' 'Markdown' rendering library (https://github.com/vmg/sundown). 'Markdown' is a plain-text formatting syntax that can be converted to 'XHTML' or other formats. See http://en.wikipedia.org/wiki/Markdown for more information about 'Markdown'.

desc

cran
97th

Percentile

Tools to read, write, create, and manipulate DESCRIPTION files. It is intended for packages that create or manipulate other packages.

remotes

cran
96th

Percentile

Download and install R packages stored in 'GitHub', 'BitBucket', or plain 'subversion' or 'git' repositories. This package is a lightweight replacement of the 'install_*' functions in 'devtools'. Indeed most of the code was copied over from 'devtools'.

naniar

cran
91th

Percentile

Missing values are ubiquitous in data and need to be explored and handled in the initial stages of analysis. 'naniar' provides data structures and functions that facilitate the plotting of missing values and examination of imputations. This allows missing data dependencies to be explored with minimal deviation from the common work patterns of 'ggplot2' and tidy data.

91th

Percentile

Query and print information about the current R session. It is similar to 'utils::sessionInfo()', but includes more information about packages, and where they were installed from.

affxparser

bioconductor
18th

Percentile

Package for parsing Affymetrix files (CDF, CEL, CHP, BPMAP, BAR). It provides methods for fast and memory efficient parsing of Affymetrix files using the Affymetrix' Fusion SDK. Both ASCII- and binary-based files are supported. Currently, there are methods for reading chip definition file (CDF) and a cell intensity file (CEL). These files can be read either in full or in part. For example, probe signals from a few probesets can be extracted very quickly from a set of CEL files into a convenient list structure.

BiocContributions

bioconductor
18th

Percentile

A set of tools for cleaning up, post-processing, adding packages to the repository, and for emailing people etc.

argufy

github
18th

Percentile

Declare your functions with argument checks, and 'argufy' will generate and add the checking code for you.

RInno

cran
18th

Percentile

Installs shiny apps packaged as stand-alone Electron apps using Inno Setup, an open source software that builds installers for Windows programs <http://www.jrsoftware.org/ishelp/>.

vapour

cran
18th

Percentile

Provides low-level access to 'GDAL' functionality for R packages. The aim is to minimize the level of interpretation put on the 'GDAL' facilities, to enable direct use of it for a variety of purposes. 'GDAL' is the 'Geospatial Data Abstraction Library' a translator for raster and vector geospatial data formats that presents a single raster abstract data model and single vector abstract data model to the calling application for all supported formats <http://gdal.org/>. Other available packages 'rgdal' and 'sf' also provide access to the 'GDAL' library, but neither can be used for these lower level tasks, and both do many other tasks.

SummarizedExperiment

bioconductor
18th

Percentile

The SummarizedExperiment container contains one or more assays, each represented by a matrix-like object of numeric or other mode. The rows typically represent genomic ranges of interest and the columns represent samples.
