Sweave - Interface entre R e LaTeX (Portuguese)

Wed, 16 Feb 2011 23:52:57 GMT

Cassiano Sousa Rosa, Og DeSouza. Resumo: É comum depararmos com o problema da gravação em arquivos separados dos comandos e dos gráficos, se o sistema estatístico R é utilizado. Outro problema seria localizar o código que originou aquele determinado gráfico. Para as pessoas que utilizam o R e também têm familiaridade com o LaTeX, agora existe uma boa solução para este problema, o Sweave.

Abstract: When using R for statistical analyses, it is common to keep the data analyses, the results of experiments, and graphs in separate files. Fortunately, for R users who also use LaTeX, there is a tool for organizing these files: Sweave! This paper presents a very short account on how Sweave integrates R and LaTeX to keep both input and output of statistical analyses in a single style file.

Scientific Presentations with LaTeX

Wed, 16 Feb 2011 23:49:06 GMT

Marius Hofert, Markus Kohm. In this article, we show how scientific presentations can be created based on the KOMA-Script document class scrartcl. The main advantage of the suggested approach is that the presentation slides allow for easy copy-and-paste of content from other LaTeX documents such as research papers or handouts. Using this approach, presentation slides are quickly generated, without the author having to learn how to use other LaTeX presentation packages. Additionally, in contrast to the rather overused templates of the more common presentation packages, the slides can be individually created and thus tailored to the topic of the presentation.

Design and Preparation of Effective Scientific Posters using LaTeX

Wed, 16 Feb 2011 23:47:34 GMT

Paulo Rogério de Souza e Silva Filho, Rian Gabriel Santos Pinheiro. Posters are important presentation tools in scientific conferences. LaTeX offers several packages, e.g. a0poster and sciposter, for designing several kinds of high quality posters. However, many of the posters we are used to seeing are visually split into columns and conceptually organized in sections, with amounts of text which are likely to disrupt the viewing experience and understanding of the content. In this article we present an efficient method for preparing visual scientific posters using the PGF package and its syntax layer TikZ.

Variation and sign tables with tableau
