The CPAN Testers Dependencies is a website that shows a chart of the test results of all dependencies for a distribution. Poloto graphs can be stylized using css either directly in the SVG. The CPAN Testers Matrix is a website that provides a visual overview of the test results for a distribution on various Perls/platforms. A simple 2D plotting library that outputs graphs to SVG that can be styled using CSS. Note that SVG is a vector graphics format, and the default png device produces a raster graphics format. For HTML output, you may consider using dev 'svg' or dev 'svglite' for SVG plots. The CPAN Testers is a network of smoke testers who run automated tests on uploaded CPAN distributions. Usually, vector graphics have higher quality than raster graphics, and you can scale vector graphics without loss of quality. 14.2.2 Solution Use svglite () from the svglite package: library (svglite) svglite ( 'myplot.svg', width 4, height 4) plot (.) dev.off () With ggsave () ggsave ( 'myplot. The CPANTS is a website that analyzes the Kwalitee ( code metrics ) of a distribution. 14.2 Outputting to SVG Vector Files 14.2.1 Problem You want to create a scalable vector graphics (SVG) image of your plot. The RT ( Request Tracker ) website is the default bug/issue tracking system for CPAN. As always, in addition to those websites please use your favorite search engine to discover more resources.Ī modern, open-source CPAN search engine, useful to view POD in HTML format. ![]() The following websites have more information about this module, and may be of help to you. Graph::Easy::As_svg contains just the code for converting a Graph::Easy object to a SVG text. (It looks fine on my Mac using recent versions of Chrome and Firefox.Graph::Easy::As_svg - Output a Graph::Easy as Scalable Vector Graphics (SVG) VERSION By the way, if you only see one image above it's because your browser doesn't support SVG. But now, most modern browsers can render high-quality SVG images using the standard tag, and R can easily generate SVG files with the svg device driver.įor example, here's a c alendar heat map of Apple stock since the beginning of 2010 rendered as a SVG:įor comparison, here's the same image rendered as a PNG:Īs you can see, the SVG file has much finer detail this will become even more apparent if you right-click on each image to view them in their own tab, or download AAPL.svg and view it directly. The SVG version (rendered at 14in wide) will show much more detail in larger format. The problem until recently is that not many browsers have had native support for vector images, limiting their usefulness on the web. Vector-based formats like PostScript and SVG always look their best regardless of the resolution, because they're rendered on demand from the component lines, symbols, and other elements of your graphic: it's a bit like using a laser printer instead of a dot-matrix printer, with a corresponding increase in quality. But if you're publishing on the Web, you're probably limited in resolution (here on the blog, I'm limited to 500px in the horizontal direction, for example). Common formats like GIF and JPG are raster-based: the image is composed of pixels, and if you don't choose a high enough resolution, you're likely to lose fine details and/or the image will look blocky. If you want the graphics you create with R to look their best, in general it's best to go for a vector-based graphics format instead of a raster-based format.
