R > Report
Create a (reproducible) report
The best way to store your work in Radiant is use to use the R > Report feature and save a state-file with all your results and settings. The report feature in Radiant should be used in conjunction with the icons shown on the bottom of the (left) side bar on all analysis pages.
The editor shown on the left in R > Report shows past commands in R-code chunks. These chunks can include R-code you typed or code generated by Radiant and added to the report after clicking an icon. All code blocks start with ```{r} and are closed by ```
By default Radiant will add the code generated for the analysis you just completed to the bottom of the report. After clicking a icon Radiant will, by default, switch to the R > Report tab. Click inside the editor window on the left and scroll down to see the generated commands. However, you can choose to select Manual paste instead or Auto paste from the appropriate drop-down in the R > Report tab. With Manual paste the code is put into the clipboard when you click and you can paste it where you want in the editor window.
You can also choose not to switch tabs after clicking a icon by selecting Don't switch tab from the appropriate drop-down in the R > Report tab.
If you started Radiant from Rstudio, you can even choose to have commands sent to an R-code or Rmarkdown document open in Rstudio by selecting To R or To Rmd respectively instead of Auto paste or Manual paste.
You can add text or additional commands to create an Rmarkdown document. An Rmarkdown file (extension .Rmd) is a plain text file that can be opened in Notepad (Windows), TextEdit (Mac), Rstudio, Sublime Text, or any other text editor. Please do not use Word to edit rmarkdown files.
Using Rmarkdown is extremely convenient because you can replicate your entire analysis very quickly without having to generate or type all commands again.
By clicking the Knit report button on the top-left of your screen, the output from the analysis will be (re)created on the right of the R > Report page. You can add text, bullets, headers, etc. around the code chunks to describe and explain the results using markdown. To evaluate only a part of the report use the cursor to select a section and press CTRL-return (CMD-return on mac) to create the (partial) output.
If you started Radiant from Rstudio you can save the report in various formats (i.e., HTML, Word, or PDF). To save the Rmarkdown file open in the editor select Rmd (or Rmd & Data) and press Save report. Note that Windows users will need to install Rtools for the Rmd & Data feature to work.
The best way to save your analyses and settings is to save the state of the application to a file by clicking on the icon in the navbar and then clicking on Save state. The state-file (extension rda) will contain (1) the data loaded in Radiant, (2) settings for the analyses you were working on, (3) and any reports or code from the R-menu. Save the state-file to your hard-disk and, when you are ready to continue, simply load it by selecting state from the Load data of type dropdown in the Data > Manage tab and clicking the Choose file button.
If you are using Radiant for a class I suggest you use the R > Report feature to complete assignments and cases. When you are done, generate an HTML (or Word or PDF) report by clicking the Save report button. Submit both the report and your state-file.
