g_index {xxdi}

g_index

Description

This function calculates the g-index for an institution using bibliometric data from an edge list, with an optional plot visualisation.

Usage

g_index(df, id, cit, plot = FALSE)

Arguments

df

Data frame object containing bibliometric data. This data frame must have at least three columns: one for keywords, one for unique IDs, and one for citation counts. Each row in the data frame should represent a document or publication.

id

Character string specifying the name of the column in "df" that contains unique identifiers for each document. Each cell in this column must contain a single ID (unless missing) and not multiple IDs.

cit

Character string specifying the name of the column in "df" that contains the number of citations each document has received. Citations must be represented as integers. Each cell in this column should contain a single integer value (unless missing) representing the citation count for the corresponding document.

plot

Logical value indicating whether to generate and display a plot of the g-index calculation. Set to "TRUE" or "T" to generate the plot, and "FALSE" or "F" to skip plot generation. The default is "FALSE".

Value

g-index value and plot for institution.

Examples

# Create an example data frame
dat1 <- data.frame(citations = c(0, 1, 1, 2, 3, 5, 8),
                   keywords = c("a; b; c", "b; d", "c", "d", "e; g", "f", "g"),
                   id = c("abc123", "bcd234", "def345", "efg456", "fgh567", "ghi678", "hij789"),
                   categories = c("a; d; e", "b", "c", "d; g", "e", "f", "g"))
# Calculate g-index
g_index(df = dat1, id = "id", cit = "citations")

# Create another example data frame
dat2 <- data.frame(citations = c(0, 1, 1, 2, 3, 5, 8),
                  keywords = c("a/ b/ c", "b/ d", "c", "d", "e/ g", "f", "g"),
                  id = c("123", "234", "345", "456", "567", "678", "789"),
                  categories = c("a/ d/ e", "b", "c", "d/ g", "e", "f", "g"))
# Calculate g-index
g_index(df = dat2, id = "id", cit = "citations", plot = FALSE)

# Create another example data frame
dat3 <- data.frame(citations = c(0, 1, 1, 2, 3, 5, 8),
                  keywords = c("a, b, c", "b, d", "c", "d", "e, g", "f", "g"),
                  id = c(123, 234, 345, 456, 567, 678, 789),
                  categories = c("a: d: e", "b", "c", "d: g", "e", "f", "g"))
# Calculate g-index and produce plot
g_index(df = dat3, id = "id", cit = "citations", plot = TRUE)
