Hi Jason, You can add as many objects as you want to save(). For instance: save(data1, data2, data3, data4, file = "whatever"). Once you have loaded the data, just add whatever data you want, and then save it (or edit your original object and resave it). Here is another example:
> ls() character(0) > load("rhelp.RData") > ls() [1] "x" > ## Now I could edit, 'x' (e.g., rbind() in additional rows, etc.) > ## or I could create a new variable, 'y' > y <- 1:10 # some new data > ## from > ?save > save(x, y, file = "rhelp.RData") > ## clear space and show it is empty > rm(list=ls()); ls() character(0) > load("rhelp.RData") > ls() [1] "x" "y" > ## now both 'x' and 'y' are in the RData file > ## if I had just edited x and resaved, it would be updated Cheers, Josh On Thu, Nov 18, 2010 at 7:26 AM, Jason Kwok <jayk...@gmail.com> wrote: > Thanks for the response Duncan. > > I'm sorry I wasn't clear in my question.
