Re: [R] Updata Rdata File
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

Re: [R] Updata Rdata File
Thanks for the response Duncan. I'm sorry I wasn't clear in my question. I need to add an additional value every day to the data and not update it. I know how to load and save but I dont' know how to add data. load(file="C:\\datafile.rdata") save(data,file="C:\\datafile.rdata") Thanks.
