The results are not inconsistent. The codes you are comparing are inconsistent!
The function Hindex has an argument "years" used to set the time span of the H-index analysis. The default value, as specified in the help, is 10 years (the means the last ten years). The collection does not include any article published by SMALL H during the last 10 years. Here is the text from the function help:
years | is an integer. It indicates the number of years to consider for Hindex calculation. Default is 10.
If you want to calculate the Hindex considering all articles published during the whole time span, you have to set years=Inf
Hlist<- Hindex(scientometrics, field = "author", elements = NULL, sep = ";", years = Inf)$H
Hlist[Hlist$Element=='SMALL H',]
Element h_index g_index PY_start TC NP m_index
152 SMALL H 7 7 1985 454 7 0.1842105
I'm getting disparate results when trying to measure the number of papers and H indices for authors in a data set. While I noticed this issue for a WoS text import, I was able to reproduce with the package's scientometrics data set. For instance in the code below, the author Small has no publications using the Hindex function and 8 publications using the biblioAnalysis function. Even when declaring the author element, the Hindex function is miscounting authorship.
