exploratory data analysis

There probably is no “one stop shop” for exploratory data analysis. I’d like to see some plots myself – box plots, cumulative distributions, time series – and why not put all those side by side with the relevant summary statistics? But still, this is a nice entry.

The describe() function from R’s psych package (Revelle, 2023) provides a comprehensive statistical summary of your dataset. Unlike R’s base summary() function, it includes additional metrics that are particularly useful for data exploration and assumption checking.

All this works best for data points you assume are independent of each other in time and space, which is not how the actual universe tends to work. And heah, I know there is a thing called machine learning, but I like to start simple to begin building a picture of a data set in my simple human brain.

bibliometrix

Bibliometrix is an R package for literature review and synthesis of past research on a topic. It now has a Shiny graphical interface.

bibliometrix: An R-tool for comprehensive science mapping analysis

The use of bibliometrics is gradually extending to all disciplines. It is particularly suitable for science mapping at a time when the emphasis on empirical contributions is producing voluminous, fragmented, and controversial research streams. Science mapping is complex and unwieldly because it is multi-step and frequently requires numerous and diverse software tools, which are not all necessarily freeware. Although automated workflows that integrate these software tools into an organized data flow are emerging, in this paper we propose a unique open-source tool, designed by the authors, called bibliometrix, for performing comprehensive science mapping analysis. bibliometrix supports a recommended workflow to perform bibliometric analyses. As it is programmed in R, the proposed tool is flexible and can be rapidly upgraded and integrated with other statistical R-packages. It is therefore useful in a constantly changing science such as bibliometrics.
