#> --------------
#>   # Seamless R and C++ Integration
#>   The 'Rcpp' package provides R functions as well as C++ classes which offer a
#>   seamless integration of R and C++. Many R data types and objects can be mapped
#>   back and forth to C++ equivalents which facilitates both writing of new code
#>   as well as easier integration of third-party libraries. Documentation about
#>   'Rcpp' is provided by several vignettes included in this package, via the
#>   'Rcpp Gallery' site at <https://gallery.rcpp.org>, the paper by Eddelbuettel
#>   and Francois (2011, <doi:10.18637/jss.v040.i08>), the book by Eddelbuettel
#>   (2013, <doi:10.1007/978-1-4614-6868-4>) and the paper by Eddelbuettel and
#>   Balamuta (2018, <doi:10.1080/00031305.2017.1375990>); see 'citation("Rcpp")'
#>   for details.

#>   # Render Markdown with the C Library 'Sundown'
#>   Provides R bindings to the 'Sundown' Markdown rendering library

#> ---------------
#>   # Boost C++ Header Files
#>   Boost provides free peer-reviewed portable C++ source libraries.  A large part
#>   of Boost is provided as C++ template code which is resolved entirely at
#>   compile-time without linking.  This package aims to provide the most useful
#>   subset of Boost libraries for template use among CRAN packages. By placing
#>   these libraries in this package, we offer a more efficient distribution system
#>   for CRAN as replication of this code in the sources of other packages is
#>   avoided. As of release 1.78.0-0, the following Boost libraries are included:
#>   'accumulators' 'algorithm' 'align' 'any' 'atomic' 'beast' 'bimap' 'bind'
#>   'circular_buffer' 'compute' 'concept' 'config' 'container' 'date_time'
#>   'detail' 'dynamic_bitset' 'exception' 'flyweight' 'foreach' 'functional'
#>   'fusion' 'geometry' 'graph' 'heap' 'icl' 'integer' 'interprocess' 'intrusive'
#>   'io' 'iostreams' 'iterator' 'lambda2' 'math' 'move' 'mp11' 'mpl'
#>   'multiprecision' 'numeric' 'pending' 'phoenix' 'polygon' 'preprocessor'
#>   'process' 'propery_tree' 'random' 'range' 'scope_exit' 'smart_ptr' 'sort'
#>   'spirit' 'tuple' 'type_traits' 'typeof' 'unordered' 'utility' 'uuid'.

#> 4 StanHeaders @ 2.21.0.7                                   Ben Goodrich, about a year ago
#> ------------------------
#>   # C++ Header Files for Stan
#>   The C++ header files of the Stan project are provided by this package, but it
#>   contains little R code or documentation. The main reference is the vignette.
#>   There is a shared object containing part of the 'CVODES' library, but its
#>   functionality is not accessible from R. 'StanHeaders' is primarily useful for
#>   developers who want to utilize the 'LinkingTo' directive of their package's
#>   DESCRIPTION file to build on the Stan library without incurring unnecessary
#>   dependencies. The Stan project develops a probabilistic programming language
#>   that implements full or approximate Bayesian statistical inference via Markov
#>   Chain Monte Carlo or 'variational' methods and implements (optionally
#>   penalized) maximum likelihood estimation via optimization. The Stan library
#>   includes an advanced automatic differentiation scheme, 'templated' statistical
#>   and linear algebra functions that can handle the automatically
#>   'differentiable' scalar types (and doubles, 'ints', etc.), and a parser for
#>   the Stan language. The 'rstan' package provides user-facing R functions to
#>   parse, compile, test, estimate, and analyze Stan models.

#> ----------------------
#>   # An Interruptible Progress Bar with OpenMP Support for C++ in R Packages
#>   Allows to display a progress bar in the R console for long running
#>   computations taking place in c++ code, and support for interrupting those
#>   computations even in multithreaded code, typically using OpenMP.

#> ---------------
#>   # A C++11 Interface for R's C Interface
#>   Provides a header only, C++11 interface to R's C interface.  Compared to other
#>   approaches 'cpp11' strives to be safe against long jumps from the C API as
#>   well as C++ exceptions, conform to normal R function semantics and supports
#>   interaction with 'ALTREP' vectors.

#> --------------
#>   # Test Coverage for Packages
#>   Track and report code coverage for your package and (optionally) upload the
#>   results to a coverage service like 'Codecov' <https://codecov.io> or
#>   'Coveralls' <https://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.

#> -----------------
#>   # Functions to Inline C, C++, Fortran Function Calls from R
#>   Functionality to dynamically define R functions and S4 methods with 'inlined'
#>   C, C++ or Fortran code supporting the .C and .Call calling conventions.

#> -------------------
#>   # Snowball Stemmers Based on the C 'libstemmer' UTF-8 Library
#>   An R interface to the C 'libstemmer' library that implements Porter's word
#>   stemming algorithm for collapsing words to a common root to aid comparison of
#>   vocabulary. Currently supported languages are Danish, Dutch, English, Finnish,
#>   French, German, Hungarian, Italian, Norwegian, Portuguese, Romanian, Russian,

#> ---------------------
#>   # R-Friendly Threading in C++
#>   Provides a C++11-style thread class and thread pool that can safely be
#>   interrupted from R. See Nagler (2021) <doi:10.18637/jss.v097.c01>.

Stemming

The search server uses the stems of the words in the indexed metadata, and the search phrase. This means that “colour” and “colours” deliver the exact same result. So do “coloring”, “colored”, etc. (Unless one is happen to be an exact package name or match another non-stemmed field.)

Ranking

The most important feature of a search engine is the ranking of the results. The best results should be listed first. pkgsearch uses weighted scoring, where a match in the package title gets a higher score than a match in the package description. It also uses the number of reverse dependencies and the number of downloads to weight the scores:

ps("colour")[, c("score", "package", "revdeps", "downloads_last_month")]
#> # A data frame: 10 × 4
#>     score package      revdeps downloads_last_month
#>     <dbl> <chr>          <int>                <int>
#>  1 17254. crayon           346              1020155
#>  2 10681. colorspace       179               621855
#>  3 10096. viridis          160               425759
#>  4  7653. pillar            66              1532564

#> 10  3479. ggnewscale        18                 6126

Preferring Phrases

The search engine prefers matching whole phrases over single words. E.g. the search phrase “permutation test” will rank coin higher than testthat, even though testthat is a much better result for the single word “test”. (In fact, at the time of writing testthat is not even on the first page of results.)

ps("permutation test")

If the whole phrase does not match, pkgsearch falls back to individual matching words. For example, a match from either words is enough here, to get on the first page of results:

British vs American English

The search engine uses a dictionary to make sure that package metadata and queries given in British and American English yield the same results. E.g. note the spelling of colour/color in the results:

ps("colour")
#> - "colour" ---------------------------------------------- 270 packages in 0.005 seconds -
#>   #     package      version by                 @ title

Ascii Folding

Especially when searching for package maintainer names, it is convenient to use the corresponding ASCII letters for non-ASCII characters in search phrases. E.g. the following two queries yield the same results. Note that case is also ignored.

ps("gabor", size = 5)
