PKGSearch使用R-Hub Web服務和仔細排名，將受歡迎的軟件包放在較少使用的軟件包之前。
對於上面提到的搜索以及Cran Metadata的其他入口點，您可以使用PKGSearch Rstudio加載項！
從菜單中選擇“ cran軟件包搜索” addin，或使用pkg_search_addin()啟動。

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

#>
#> 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.

#>
#> 5 glpkAPI @ 1.3.4 Mihail Anton, about a year ago
#> -----------------
#> # R Interface to C API of GLPK
#> 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.
#> https://github.com/trevorld/r-getopt
#>
#> 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.
#> <https://dnalytics.com/software/liblinear/>
#>
#> 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".

搜索服務器使用索引元數據中的單詞的詞乾和搜索短語。這意味著“顏色”和“顏色”產生完全相同的結果。 “顏色”，“彩色”等也是如此（除非一個恰好是一個精確的軟件包名稱或匹配另一個非莖字段。）

搜索引擎的最重要特徵是結果的排名。最好的結果應首先列出。 PKGSearch使用加權評分，其中軟件包標題中的匹配比軟件包描述中的匹配項更高。它還使用反向依賴的數量和下載次數來加權分數：
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
#> 7 1546. colorizer 1 1
#> 8 1496. munsell 3 1
#> 9 1463. colouR 1 1
#> 10 1457. plotrix 62 1
搜索引擎更喜歡將整個短語匹配而不是單個單詞。例如，即使Testthat對於單個單詞“ Test”是更好的結果，搜索短語“排列測試”的排名將高於TestThat。 （實際上，在編寫時，testthat甚至不在結果的第一頁上。）
ps( " permutation test " ) #> - "permutation test" ----------------------------------- 2545 packages in 0.048 seconds -

如果整個短語不匹配，則PKGSearch將返回到單個匹配的單詞。例如，這兩個單詞的匹配就足夠了，可以進入結果的首頁：
