![]() ![]() If you are interested in learning more about using Rust in R packages, have a look at my slides from eRum 2018. #Install gifski r code#In this case the R package itself does not contain any Rust code because we can call Rust directly from C. This is the first CRAN package that interfaces a Rust library. Either provide input png files, or automatically render animated graphics from the R graphics. Hopefully this will make it easier to generate animations with hundreds or even thousands of frames using for example the gganimate package. Gifski converts image frames to high quality GIF animations. Running this example shows that the GIF encoding is no longer a serious overhead: time spent in encoding is only a small fraction of the total time to generate the plot. Gifski shows a progress meter while generating the GIF. Scale_x_log10(limits = range(gapminder$gdpPercap)) + ggtitle(data$year) + theme_classic() Scale_size("population", limits = range(gapminder$pop)) + geom_point() + ylim(20, 90) + The above example converts 'video.mp4' file to GIF (replace the path with your videos actual path. gifski -fps 10 -width 320 -o anim.gif video.mp4. The CLI version must be run from a command line (a terminal, cmd.exe). #Install gifski r install#P <- ggplot(data, aes(gdpPercap, lifeExp, size = pop, color = continent)) + You can also get it with cargo install gifski if you have Rust installed. animation::saveGIF() but much faster: # Example borrowed from gganimateĭatalist <- split(gapminder, gapminder$year) Png_files <- sprintf("frame%03d.png", 1:10)Īlternatively the save_gif() function captures plots R generated in an R expression and saves them as a animated gif, just like e.g. The gifski() function combines a set of PNG images into a single animated GIF file: # Convert png files to gif #Install gifski r manual#The ?gifski manual page contains example of both. The R interface is very simple: either generate a GIF from a set of images, or directly from the R graphics device. If you are on MacOS, try installing from source to see how it works: install.packages("gifski", type = "source") Cargo automatically compiles and links all Rust code when building the R package. On Linux you need to install cargo to compile the rust code, but the package does not require any external libraries. One of the major benefits of Rust is that it has no runtime, so the R package has no dependencies. The R package wraps the Rust crate and can be installed in the usual way from CRAN. The Gifski Website has more technical details and beautiful examples. ![]() It can create animated GIF images with thousands of colors per frame and do so much faster than other software. Gifski is a multi-threaded high-quality GIF encoder written in Rust. Gifski is a simple but powerful package which can hopefully take away an important performance bottleneck for generating animated graphics in R. The gifski package which was demonstrated in May at eRum 2018 in Budapest is now on CRAN. ![]()
