Summaries of a bibliographic database

summary() methods for bibliometric databases.

Usage

# S3 method for class 'wos.db'
summary(object, filter, index = c("H", "G"), nmax = 10, ...)

# S3 method for class 'summary.wos.db'
print(x, ...)

author_metrics(db, id_authors)

# S3 method for class 'summary.wos.db'
plot(
  x,
  which = 1:5,
  pie = FALSE,
  others = !pie,
  accuracy = 0.1,
  plot = TRUE,
  ask = length(which) > 1 && interactive(),
  ...
)

# S3 method for class 'wos.jcr'
summary(object, filter, all = FALSE, ...)

# S3 method for class 'summary.wos.jcr'
print(x, digits = 2, all = TRUE, ...)

# S3 method for class 'summary.wos.jcr'
plot(x, plot = TRUE, all = FALSE, ask = plot && all && interactive(), ...)

Arguments

object

an object for which a summary is desired.

filter

vector of document identifiers (optional, usually a result of get_id_docs()).

index

citation indexes.

nmax

number of top levels.

...

further arguments passed to or from other methods.

x

an object used to select a method.

db

Object of class wos.db, as returned by db_bib.

id_authors

optional; author identifiers

which

if a subset of the plots is required, specify a subset of the numbers 1:5.

pie

logical; if TRUE, pie charts are drawn.

others

logical; if FALSE, only nmax top levels categories are shown.

accuracy

numerical scalar; see label_number(accuracy=.).

plot

logical; if TRUE (default), the plots are drawn, otherwise only the list of ggplot2 objects is (invisibly) returned.

ask

logical; if TRUE, the user is asked before each plot, see par(ask=.).

all

logical; if TRUE, the corresponding wos.db method is called (additional parameters ... are passed to it), otherwise only results of JCR metrics are returned.

digits

minimal number of significant digits, see print.default.

Value

A list of summary statistics (an object of class summary.wos.db or summary.wos.jcr), which have specialized print() and plot() methods.
