It calculates the percentage of missing data in the metadata of a bibliographic data frame.
missingData(M)The function missingData returns a list containing two objects:
allTags | is a data frame including results for all original metadata tags from the collection | |
mandatoryTags | is a data frame that included only the tags needed for analysis with bibliometrix and biblioshiny. |
is a bibliographic data frame obtained by convert2df function.
Each metadata is assigned a status c("Excellent," "Good," "Acceptable", "Poor", "Critical," "Completely missing") depending on the percentage of missing data. In particular, the column *status* classifies the percentage of missing value in 5 categories: "Excellent" (0 "Poor" (from 20.01
The results of the function allow us to understand which analyses can be performed with bibliometrix and which cannot based on the completeness (or status) of different metadata.
data(scientometrics, package = "bibliometrixData")
res <- missingData(scientometrics)
