Ctrl+K will kill all the text to the right of the cursor [including the end-of-line character] and Ctrl+Y will yank it back [paste it in]). info makes many longtime R users happy—it is hard to retrain one’s fingers! Similar shortcuts have been present for a long time in R’s console through the readline library. In Table 1-2, we listed shortcuts for navigation between components. Here in Table 3-1, we describe shortcuts for working at the console, and in Table 3-2 list the available shortcuts for sending commands from the source-code editor to the console.
Once a file is specified (and possibly downloaded/uploaded), a dialog appears that allows you to customize how the data will be imported. Figure 3-15 shows the defaults for reading in the mtcars data when first written out as a csv file. Figure 3-15. char. For server usage, one can upload arbitrary files into the working directory through the Files browser (see “The File Browser” on page 71). The Help Page Viewer As mentioned, R is enhanced by external code organized into packages. Packages are a structured means for the functions and objects that extend R.
For packages on CRAN, compliance is checked automatically. Each exported function should be documented in a help page. This page typically contains a description of the function, a description of its arguments, additional information potentially of use to the user, and, optionally, some example code. Multiple functions may share the same documentation file. In addition to examples for a function, a package may contain demos to illustrate key functionality and vignettes (longer documents describing the package and what it provides).
