h Index Over Years

The hIndex pkg. gets graphical representation of the h Index over the years for a given author.

This R-package is motivated by the reading of How does a scientist’s h-index change over time?, by Jeff Ollertons, Professor of Biodiversity in the Department of Environmental and Geographical Sciences at the University of Northampton. It is a great post and I highly recommend it.

By using hIndex you will be able to:


Installation

Install the pkg. in three simple steps:

Step1. You need to install the devtools package.

install.packages("devtools")

Step2. Load the devtools package.

library(devtools)

Step3. Install the hIndexOverYears package.

install_github("jdieramon/hIndex")

Usage

Load the package …

library(hIndexOverYears)
#> Loading required package: dplyr
#> 
#> Attaching package: 'dplyr'
#> The following objects are masked from 'package:stats':
#> 
#>     filter, lag
#> The following objects are masked from 'package:base':
#> 
#>     intersect, setdiff, setequal, union
#> Loading required package: ggplot2

… and use it !

The function clean will read and clean the data from SCOPUS.

dat <- clean("../CTOExport.csv")

Use the h.plot function on the tidy data to show the h Index evolution over years. If the starting year does not correspond with h=0, you can enter the h value as an argument:

h.plot(dat, 2007, 2018, 0)
#> 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 2018 
#>    0    1    3    3    4    5    6    7    8   11   11   12

You may also want to use the get1cite function to list your most highly cited papers (top10) and get a sense of how long it takes each of them to get 1 citation. The function shows by default your top10 cited papers, but you can give the number of papers as an argument.

get1cite(dat)
#>    Year                                     Journal avgMonth
#> 1  2010                                      Planta     1.07
