R help - Jul 2018 - Saving objects in RData file in different name

Hi,

Let say I have 2 objects as below

x1 = 1:3
x2 = 5:4

Now I want to save both x1 and x2 in some RData file, however x1 will be
saved with a different name e.g. y

I tried below

save(y = x1, x2, file = "file.RData")

However still they are saved in their original names i.e. x1 and x2, not y
and y2.

Is there any possibility that I can achieve above without explicitly
copying y = x1 before y is passed to save()

Thanks for any feedback.

Hi!

Maybe not the most elegant solution, but a workaround is to have a
function:
> save2<-function(y, ...) { save(y,...)}
> save2(x1,x2,file="test.RData")
The point is to include the variables to be "renamed" as parameters
(in
my example: y). The function will use the parameter variable names when
saving the file.

Kimmo

Hello

In case you have conflicting data issue when you load data, you can also do it
the other way around. Indeed you never know when a possible conflict might occur
in the future.
The following line load the data in a new environment e first then get it back
to your current environment.

loaded..data <- get(load("test.RData",e<- new.env()),e)

you might then want to remove everything in that enviromnent afterwards,

rm(list=ls(envir=e1), envir=e1)

Hi!

In those cases, I use R.utils::saveObject() and loadObject().
You would have to save each object separately though:

saveObject(x1, file="file.Rbin")
y <- loadObject(file="file.Rbin")
