If you are creating R charts in an RMarkdown environment with HTML output (such as RStudio), simply printing a graph you created using the plotly R package in a code chunk will result in an interactive HTML graph in the viewer.. When I first started using RMarkdown, it felt very much like a blessing. Ideally, the solution should work independently of the output, and without having to write CSS code (CSS! You can also place plots side by side if the sum of the width of all plots is smaller than or equal to the current line width. RMarkdown is awesome! If you create the plot and save it, but do not print it in the document, then you will not be able to reference the plot or table. Embed an interactive D plot with rgl . Thanks! You need to make sure that you actually print the table or plot. We can use the knitr function include_graphics which is convenient, as it takes care for the different output formats and provides some more features (see here the help file).. ### Simple plot: Here is a basic plot using base graphics: ```{r } plot(x) ``` ```{r simpleplot} plot(x) ``` Note that unlike traditional Sweave, there is no need to write `fig=TRUE`. Note that online sources are allowed. Show the chunk header in the output . Keyboard shortcuts are available for these options. Embedding R Graphs in RMarkdown files. Don`t forget to load knitr previously. How to solve. If all fails. If you want to put multiple plots in one figure environment, you must use the chunk option fig.show = 'hold' to hold multiple plots from a code chunk and include them in one environment. You can simply return a plot in a chunk, and knitr will automatically write the files to disk, in an organized subfolder. By specifying options in the setup chunk, you can have R automatically save your plots in multiple file formats at once, including PNG, PDF, and SVG. Miscellaneous knitr Tricks ; Reuse code chunks . By chunk: You can run the entire chunk (or multiple chunks) by clicking on the Chunks dropdown button in the upper right corner of the script environment and choosing the appropriate option. Embed one chunk in another chunk (*) Use the same chunk label in another chunk . Not only does the format encourage reproducible analysis by enabling you to interweave code, text, images, and plots, it also allows you to knit() the document into so many different formats, including static HTML, MS Word, PowerPoint, PDF - everything done from the comfort of the RStudio IDE! As already mentioned, any loop needs to be in a code chunk. Realistically, a solution which at least works with HTML output will still be ok. Report how much time each chunk takes to run . There isn’t one - you just get \@ref(fig:figure-chunk-name) printed. Click the links below to see more options. I would like to show two images stacked horizontally in a R Markdown report, but, no matter how much I downsize them, R Markdown keeps stacking them horizontally. The graphical parameter fig lets us control the location of a figure precisely in a plot.. We need to provide the coordinates in a normalized form as c(x1, x2, y1, y2).For example, the whole plot area would be c(0, 1, 0, 1) with (x1, y1) = (0, 0) being the lower-left corner and (x2, y2) = (1, 1) being the upper-right corner.. ). Any suggestions? It might be easier to to give the histogram a title rather than add a line of text as a header for each one. More Precise Control. For the web, using the rmarkdown default of 96dpi should be adequate except for retina screens where you may want to use a multiplier in the form of the fig.retina argument (see below). When compiling, in case there are multiple entries, the compiler will only look to the first one. A neat feature of knitr is how much simpler it makes generating figures. The "run" button in RStudio allows you to run a chunk individually or to run all chunks at once. Click the links below to see more options. When you change the dpi of an R-generated plot, larger numbers result in a larger plot unless other arguments like out.width are specified. Optimize PNG plots . Loop in R markdown (2) .
