The ‘safemode’ package provides a safemode() function that creates a “safe mode” session in R. In “safe mode”, all symbols have an “age” (a last-modified time stamp) and a set of dependent symbols, and a warning is issued whenever a symbol is used in an expression and its age exceeds the age of any of its dependents (i.e., there is warning whenever a “stale” symbol is used in an expression).
This document describes several different techniques for including SVG images within a web page and points out the important SVG attributes that control the final appearance of the SVG image within the web page. The document then describes how to control those attributes when generating SVG images with the ‘gridSVG’ package for R.
This articles explores the problem of helping people connect with data. In the first section I examine the importance of connecting people with data, and look at why people are not fully connected with data at present. In the second section I consider how software can contribute to solving this problem, and examine some software examples which may contribute to the solution. In the third section I give details of how the OpenAPI project intends to solve the problem.

The National Climate Database contains data collected from around
6,500 weather stations throughout New Zealand, providing a necessary
repository for any study involving New Zealand’s weather or climate.
Although data from this database can be accessed via a web portal (CliFlo),
the vast amount of information is not readily consumable. The clifro
R package provides the necessary functions to easily integrate the
National Climate Database with R, and provides a variety of elegant plotting
methods for data exploration. Also, by supplying functions to access the
database via CliFlo programmatically, clifro allows for transparent and
reproducible research when using these data.

The OpenAPI project attempts to make it easier to connect people with data. This document discusses some of the challenges faced in connecting people with data, and how OpenAPI addresses these challenges. It describes the technical specifications of the OpenAPI architecture, and provides some examples of OpenAPI in action. This document also discusses projects similar to OpenAPI, and how OpenAPI is distinct from these.

The gridGraphics package provides a function, grid.echo(), that can be used to convert a plot drawn with the graphics package to the same result drawn using grid. This provides access to a variety of grid tools for making customisations and additions to the plot that are not possible with the graphics package.
Reproducible documents provide an efficient way to produce reports by automatically generating content from code chunks within the report. The processing of a source document, that contains code chunks, to a final document, that contains automatically-generated content, is typically one way, with the resulting report being read-only. This report describes an experiment that attempts to make the final report document modifiable and attempts to invert the process from final document back to source document so that the modifications to the final document can be efficiently conveyed back to the original author of the report.
