Use save() to write data or any object to a file in your working directory. For example,
> save(mydata, file = "mydata.RData") # Saves `mydata' to `mydata.RData' # in your working directory. > save.image() # Saves your entire workspace to # the default `.RData' file.R will also prompt you to save your workspace when you use the q() command to quit. When you start R again, it will load the previously saved workspace. Restarting R will not, however, load previously used packages. You must remember to load Zelig at the beginning of every R session.
Alternatively, you can recall individually saved objects from .RData files using the load() command. For example,
> load("mydata.RData")loads the objects saved in the mydata.RData file. You may save a data frame, a data frame and associated functions, or other R objects to file.
