#> 1 Rcpp @ 1.0.12 Dirk Eddelbuettel, 3 months ago
#> ---------------
#> # 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.

#> 2 BH @ 1.84.0.0 Dirk Eddelbuettel, 3 months ago
#> ---------------
#> # 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 1.84.0-0, 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' 'qvm' 'random' 'range' 'scope_exit' 'smart_ptr'
#> 'sort' 'spirit' 'tuple' 'type_traits' 'typeof' 'unordered' 'url' 'utility'
#> 'uuid'.

#> 3 inline @ 0.3.19 Dirk Eddelbuettel, 3 years ago
#> -----------------
#> # Functions to Inline C, C++, Fortran Function Calls from R

#> 4 SnowballC @ 0.7.1 Milan Bouchet-Valat, about a year ago
#> -------------------
#> # 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 Arabic, Basque, Catalan, Danish,
#> Dutch, English, Finnish, French, German, Greek, Hindi, Hungarian, Indonesian,
#> Irish, Italian, Lithuanian, Nepali, Norwegian, Portuguese, Romanian, Russian,
#> Spanish, Swedish, Tamil and Turkish.

#> R Interface to C API of GLPK, depends on GLPK Version >= 4.42.
#>
#> 6 RcppProgress @ 0.4.2 Karl Forner, 4 years ago
#> ----------------------
#> # 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.
#> https://github.com/kforner/rcpp_progress
#>
#> 7 getopt @ 1.20.4 Trevor L Davis, 7 months ago
#> -----------------
#> # C-Like 'getopt' Behavior
#> Package designed to be used with Rscript to write '#!' shebang scripts that
#> accept short and long flags/options. Many users will prefer using instead the
#> packages optparse or argparse which add extra features like automatically
#> generated help option and usage, support for default values, positional
#> argument support, etc.

#>
#> 8 boot @ 1.3.30 Alessandra R. Brazzale, 2 months ago
#> ---------------
#> # Bootstrap Functions (Originally by Angelo Canty for S)
#> Functions and datasets for bootstrapping from the book "Bootstrap Methods and
#> Their Application" by A. C. Davison and D. V. Hinkley (1997, CUP), originally
#> written by Angelo Canty for S.
#>
#> 9 LiblineaR @ 2.10.23 Thibault Helleputte, 4 months ago
#> ---------------------
#> # Linear Predictive Models Based on the LIBLINEAR C/C++ Library
#> A wrapper around the LIBLINEAR C/C++ library for machine learning (available
#> at <https://www.csie.ntu.edu.tw/~cjlin/liblinear/>). LIBLINEAR is a simple
#> library for solving large-scale regularized linear classification and
#> regression. It currently supports L2-regularized classification (such as
#> logistic regression, L2-loss linear SVM and L1-loss linear SVM) as well as
#> L1-regularized classification (such as L2-loss linear SVM and logistic
#> regression) and L2-regularized support vector regression (with L1- or
#> L2-loss). The main features of LiblineaR include multi-class classification
#> (one-vs-the rest, and Crammer & Singer method), cross validation for model
#> selection, probability estimates (logistic regression only) or weights for
#> unbalanced data. The estimation of the models is particularly fast as compared
#> to other libraries.

#>
#> 10 lme4 @ 1.1.35.3 Ben Bolker, 6 days ago
#> ------------------
#> # Linear Mixed-Effects Models using 'Eigen' and S4
#> Fit linear and generalized linear mixed-effects models. The models and their
#> components are represented using S4 classes and methods. The core
#> computational algorithms are implemented using the 'Eigen' C++ library for
#> numerical linear algebra and 'RcppEigen' "glue".

El servidor de búsqueda utiliza los votos de las palabras en los metadatos indexados y la frase de búsqueda. Esto significa que el "color" y los "colores" ofrecen exactamente el mismo resultado. También lo hagan "colorante", "coloreado", etc. (a menos que uno sea un nombre exacto en el paquete o coincida con otro campo no con tallo).

La característica más importante de un motor de búsqueda es la clasificación de los resultados. Los mejores resultados deben enumerarse primero. PKGSearch utiliza puntuación ponderada, donde una coincidencia en el título del paquete obtiene una puntuación más alta que una coincidencia en la descripción del paquete. También utiliza el número de dependencias inversas y el número de descargas para peso los puntajes:
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 6717. colorspace 71 1
#> 2 3442. shape 19 1
#> 3 2490. dichromat 7 1
#> 4 2110. RColorBrewer 130 1
#> 5 1632. crayon 3 1
#> 6 1631. colorRamps 3 1

#> 8 1496. munsell 3 1
#> 9 1463. colouR 1 1
#> 10 1457. plotrix 62 1
El motor de búsqueda prefiere que coincidan las frases completas sobre palabras individuales. Por ejemplo, la frase de búsqueda "Prueba de permutación" clasificará la moneda más alta que la prueba, aunque la prueba es un resultado mucho mejor para la "prueba" de una sola palabra. (De hecho, al momento de la escritura, la prueba no está ni siquiera en la primera página de resultados).
ps( " permutation test " ) #> - "permutation test" ----------------------------------- 2545 packages in 0.048 seconds -

Si toda la frase no coincide, PKGSearch recurre a palabras coincidentes individuales. Por ejemplo, una coincidencia de cualquiera de las palabras es suficiente aquí, para ingresar a la primera página de resultados:

Especialmente cuando se busca nombres de mantenedores de paquetes, es conveniente usar las letras ASCII correspondientes para caracteres no ASCII en frases de búsqueda. Por ejemplo, las siguientes dos consultas producen los mismos resultados. Tenga en cuenta que el caso también se ignora.
