If you call save.image on its own, the history of commands will not be saved, however. RData file in your working directory rather than waiting to the end. So you can also call save.image() in the middle of a session to save everything to the. So you can actually access all of your data that you saved when you exited by loading the. In fact, when you save when exiting, R is actually calling the function save.image, which saves all of the objects to a file ".RData" in your working directory. Sometimes you want to backup your entire session in the middle, in case something crashes, etc. Except for any plots, everything is as if you just left it. Of course, if you save at the dialog box prompt when you exit R, you don't need to load the informationīack in, because the object "Numb" and any other objects you made are saved. See explanation at the end of my Introduction to R Lab This includes the prompt (">"), so this is not good for redoing commands.
#Rstudio commands windows
If you make the extension of your file ''.rdata'' then Windows recognizes If you want to save on particular object that you made (like a dataset) for use in R later, you can use the command However, this is easier to explain if we first learn about saving objects. For example, you might want to remember what that data xinc was for before you deleted it or so you don't have memory problems, particularly if you are working off of Leland and thus may run out of space. If you use R a lot, you might find that for some projects or classes you would like your objects for that project/class accessible in separate folders. Here's some translation (the Unix commands are not always exactly equivalent, so you should check out the R help): R has many commands that allow you to navigate files and directories, like on Unix, only the commands are generally NOT the same. If you want to change directories, you can use the setwd() command or if you are in the Windows GUI, you go to "File." and then click on "Change dir"
If you are entering a directory path you can use " Note that R uses "/" to separate directories (like unix) and not the Windows' " You can find what directory you are in with the getwd() command: If you just double-click from the desktop, you probably don't know what directory you are using - R starts in the default directory. Warning: Many parts of this may be Windows specific. This is not how you would export a ame so that you could give it to someone to read as a spreadsheet, for example (for which you would want write.table maybe) However, this is for manipulating R objects, which are meant to be read and handled in R. This tutorial gives some useful commands for working with R objects.
#Rstudio commands zip
Or perhaps you have run out of room on your Stanford account and need to delete your R objects, but would like to save some of them separately and zip them up. If you become a frequent user of R, you may find that you want to get some object that you made in R and move it to a different computer to work on it.
