B.5 Filtrado

Se combinan las funciones get.id<Tabla>() (se puede emplear cualquier variable de la correspondiente tabla; multiple conditions are combined with &, see e.g. dplyr::filter()) con la función get.idDocs().

B.5.1 Funciones get

  • get.idAuthors(): buscar id (códigos) de autores

    Buscar un autor concreto:

    idAuthor <- get.idAuthors(db, AF == "Cao, Ricardo")
    idAuthor
    ## Cao, Ricardo 
    ##           16

    Buscar en nombres de autores:

    idAuthors <- get.idAuthors(db, grepl('Cao', AF))
    idAuthors
    ##           Cao, Ricardo Cao-Rial, Maria Teresa 
    ##                     16                     69
  • get.idAreas(): Devuelve códigos de las áreas

    get.idAreas(db, SC == 'Mathematics')
    ## Mathematics 
    ##          16
    get.idAreas(db, SC == 'Mathematics' | SC == 'Computer Science')
    ## Computer Science      Mathematics 
    ##                7               16
  • get.idCategories(): códigos de las categorías

    get.idCategories(db, grepl('Mathematics', WC))
    ##                                 Mathematics 
    ##                                          28 
    ##                        Mathematics, Applied 
    ##                                          29 
    ## Mathematics, Interdisciplinary Applications 
    ##                                          30
  • get.idJournals() códigos de las revistas

    ijss <- get.idJournals(db, SO == 'JOURNAL OF STATISTICAL SOFTWARE')
    ijss
    ## JOURNAL OF STATISTICAL SOFTWARE 
    ##                             134
    knitr::kable(db$Journals[ijss, ], caption = "JSS")

    ## JOURNAL OF STATISTICAL SOFTWARE 
    ##                             134

B.5.2 Obtener documentos (de autores, revistas, …)

Los indices anteriores se pueden combinar en get.idDocs()

idocs <- get.idDocs(db, idAuthors = idAuthor)
idocs
##  [1]  10  16  23  33  40  56 128 183 187 196 210 220 269 286 295 312 315 332 340
## [20] 346 347 350 359 362 372 375 384 385

Los índices de documentos se pueden utilizar como filtro p.e. en summary.wos.db().
