Various R programming tools for plotting data, including: - calculating and plotting locally smoothed summary function, - enhanced versions of standard plots, - manipulating colors, - calculating and plotting two-dimensional data summaries, - enhanced regression diagnostic plots, - formula-enabled interface to 'stats::lowess' function, - displaying textual data in plots, - plotting a matrix where each cell contains a dot whose size reflects the relative magnitude of the elements, - plotting "Venn" diagrams, - displaying Open-Office style plots, - plotting multiple data on same region, with separate axes, - plotting means and confidence intervals, - spacing points in an x-y plot so they don't overlap.
A comprehensive package for structural multivariate function estimation using smoothing splines.
Tools to make it easier to work with "tables" of 'grobs'.
Functions to assist in R programming, including: - assist in developing, updating, and maintaining R and R packages, - calculate the logit and inverse logit transformations, - test if a value is missing, empty or contains only NA and NULL values, - manipulate R's .Last function, - define macros, - detect odd and even integers, - convert strings containing non-ASCII characters (like single quotes) to plain ASCII, - perform a binary search, - sort strings containing both numeric and character components, - create a factor variable from the quantiles of a continuous variable, - enumerate permutations and combinations, - calculate and convert between fold-change and log-ratio, - calculate probabilities and generate random numbers from Dirichlet distributions, - apply a function over adjacent subsets of a vector, - modify the TCP_NODELAY flag for socket objects, - efficient 'rbind' of data frames, even if the column names don't match, - generate significance stars from p-values, - convert characters to/from ASCII codes.
Binning and plotting functions for hexagonal bins.
Syntax highlighter for R code based on the results of the R parser. Rendering in HTML and latex markup. Custom Sweave driver performing syntax highlighting of R code chunks.
Provides syntax highlighting for R source code. Currently it supports LaTeX and HTML output. Source code of other languages is supported via Andre Simon's highlight package (http://www.andre-simon.de).
Tools for HTML generation and output.
A framework for creating HTML widgets that render in various contexts including the R console, 'R Markdown' documents, and 'Shiny' web applications.
Provides low-level socket and protocol support for handling HTTP and WebSocket requests directly from within R. It is primarily intended as a building block for other packages, rather than making it particularly easy to create complete web applications using httpuv alone. httpuv is built on top of the libuv and http-parser C libraries, both of which were developed by Joyent, Inc.
