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.idSources() códigos de otras fuentes (como resvistas)

  get.idSources(db, SO == 'JOURNAL OF STATISTICAL SOFTWARE')

  ## [1] 70

  # get.idSources(db, JI == 'J. Stat. Softw.')

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().
