contentanalysis vs rphylopic
A side-by-side editorial comparison of contentanalysis and rphylopic — release velocity, themes, recent moves, and the top alternatives to consider.
Shared themes:r-package
contentanalysis vs rphylopic: at a glance
What is contentanalysis?
A scientific-text analysis package moved from counting citations to classifying argument structure.
contentanalysis parses scientific papers from PDF and analyses their content — citation clustering, reference extraction and matching, word distribution, TF-IDF summaries by section. The most recent release adds a different kind of analysis: sentence-level classification of rhetorical moves, built on Swales' CARS model and extended to literature review and discussion sections, using rules by default with an optional Google Gemini path. PDF handling has been reworked in parallel for multi-column layouts and running header removal.
What is rphylopic?
The R package that puts organism silhouettes on plots keeps widening where they can be drawn.
rphylopic fetches PhyloPic silhouettes and places them into R graphics — base plots, ggplot2 layers, legends, and now phylogenetic trees and igraph networks. The 1.x line has been consistent about two things: adding a new plotting context per release, and steadily replacing its early sizing vocabulary with explicit width and height arguments. Attribution handling is unusually developed for a package this size, with permalinks and per-image credit built into the retrieval functions.

◆ Current state
contentanalysis parses scientific papers from PDF and analyses their content — citation clustering, reference extraction and matching, word distribution, TF-IDF summaries by section. The most recent release adds a different kind of analysis: sentence-level classification of rhetorical moves, built on Swales' CARS model and extended to literature review and discussion sections, using rules by default with an optional Google Gemini path. PDF handling has been reworked in parallel for multi-column layouts and running header removal.
◆ Where it's heading
The arc runs from surface features toward discourse structure. Early releases were about getting references matched correctly and plots readable; the current one asks what function each sentence performs in the argument, which is a categorically harder question and one the package answers with rules first and a language model second. The optional-LLM design is worth noting for what it avoids — the analysis still runs without an API key, and the package has already had to prune retired Gemini model versions once, which is the maintenance cost of depending on a hosted model. Reference parsing is being made format-aware rather than pattern-guessing, with CrossRef enrichment filling in what the PDF omits.
◆ Prediction
Expect the rhetorical move classification to widen to more section types and the rule-based path to keep being the default, given the package has already been forced to track model deprecations on the optional one.
rphylopic
0.0ANALYTICS
The R package that puts organism silhouettes on plots keeps widening where they can be drawn.
◆ Current state
rphylopic fetches PhyloPic silhouettes and places them into R graphics — base plots, ggplot2 layers, legends, and now phylogenetic trees and igraph networks. The 1.x line has been consistent about two things: adding a new plotting context per release, and steadily replacing its early sizing vocabulary with explicit width and height arguments. Attribution handling is unusually developed for a package this size, with permalinks and per-image credit built into the retrieval functions.
◆ Where it's heading
Development is expanding the set of places a silhouette can appear rather than changing what the package does. Base plots came first, then ggplot2 aesthetics and legend glyphs, then trees, then network vertices via an igraph shape registered automatically when both packages load. The other running thread is defensive maintenance against upstream churn: retries on failed API calls, fixes for ggplot2 4.0.0, and now an in-memory cache so repeated calls stop hammering the PhyloPic API. The ysize and size deprecation, opened in 1.5.0, is now complete and the arguments are scheduled for removal.
◆ Prediction
The deprecated ysize and size arguments look set to be removed in the next release, and on the pattern of the last four, another plotting context is a likelier addition than a change to the retrieval layer.
