bibliometrixfullname: Comprehensive Science Mapping Analysis

Description Usage Arguments Value Examples

It calculates yearly occurrences of top keywords/terms.

1	KeywordGrowth(M, Tag = "ID", sep = ";", top = 10, cdf = TRUE)

`M`	is a data frame obtained by the converting function `convert2df`. It is a data matrix with cases corresponding to articles and variables to Field Tag in the original WoS or SCOPUS file.
`Tag`	is a character object. It indicates one of the keyword field tags of the standard ISI WoS Field Tag codify (ID or DE) or a field tag created by `termExtraction` function (TI_TM, AB_TM, etc.).
`sep`	is the field separator character. This character separates strings in each keyword column of the data frame. The default is `sep = ";"`.
`top`	is a numeric. It indicates the number of top keywords to analyze. The default value is 10.
`cdf`	is a logical. If TRUE, the function calculates the cumulative occurrences distribution.
