Thematic Evolution and Thematic Map with Time Slices #140

Closed MohamedaliS closed 4 years ago

MohamedaliS commented 4 years ago

Dear Professor, Thank you for this wonderful package. I used the Bibliometrix version 2.3.1 and 3.0.0 (Biblioshiny) in my research article to analyse the Thematic Evolution and Thematic map with a 20 years (2000-2019) data. Used 4 cutting points of 2003, 2007, 2011 & 2015. The article is accepted in a Journal and in the final page proof stage. Now, the journal asked me to provide the figures in an editable format (jpg/png) in 300 DPI resolution or above. But, the outputs from biblioshiny is too low in DPI. I tried to do it in Rstudio, but unable to find the codes/examples for plotting thematic maps for each time slice. So, please provide me the R code for Word Dynamics - Word Growth (author's Keywords), thematic evolution, and thematic map for each time slice and saving them in 300 DPI or above.

With Thanks & Regards Dr Ali

Considering the function example:

library(bibliometrix)
data(scientometrics)
years=c(2000)
nexus <- thematicEvolution(scientometrics,field="ID", years=years, n=100,minFreq=2)

the object nexus contains the plots (one for each period in ggplot2 format) i.e. the first map is: nexus$TM[[1]]$map

you can use R commands to export the plot with the desired dpi.

The function for word dynamics is keywordGrowth() Please, have a look at the function help and examples ?keywordGrowth
