Merging RData files

Steven Yen
I ran two separate hours-long projects. Results of each were saved to
two separate .RData files.
Content of each includes, among others, the following:

                    me    se      t     p sig
pc21.age        0.640 0.219  2.918 0.004 ***
pc21.agesq      0.000 0.000    NaN   NaN
pc21.inc        0.903 0.103  8.752 0.000 ***
pc21.incsq      0.000 0.000    NaN   NaN
pc21.sei10      0.451 0.145  3.122 0.002 ***
pc21.sblkprot  -4.334 3.387  1.280 0.201
...

Question: How can I combine/consolidate the two .RData files into one?
Thank you.

Load both of them, produce the object you want to save, and save it. If
some objects have the same names in both files, do this carefully:  the
second load will overwrite the first one.  A safe way to do it is
described here:  https://www.r-bloggers.com/safe-loading-of-rdata-files-2/

Huh.

I may by completely wrong but you cannot do such "merging". .RData files are AFAIK places where all objects from given session are stored.

However you could load each .RData file and save/export result (one object).

BTW, what do you mean exactly by "combine/consolidate"?

And finally, post your questions in plain text not html, otherwise they can be mangled.

Cheers
Petr

Re: Merging RData files

Steven Yen
Hi all,
This is great. Again, here is what I need. I run two separate jobs (a.R
and b.R) with results (say regression outputs) going to a.RData and
b.RData. I like to put all results in one place (where I can retrieve
them in one place, ab.RData). The following codes do it (I am not sure
if line 2 is needed but I am happy). Thank you all.

load("a.RData")
save.image("ab.RData")
load("b.RData")
save.image("ab.RData")

That's the same as

load("a.RData")
load("b.RData")
save.image("ab.RData")

because the second saved image overwrites the first one.  It'll be okay
if all the variable names are different in a.RData and b.RData, but will
lose values from a.RData if any of them have the same names as objects
in b.RData.  See the link I posted earlier to avoid this.

Re: Merging RData files

Steven Yen
Understood. In my case, a.RData and b.RData contain identical
variables/data, plus simulation outputs from separate runs. The codes
deliver what I need. Good to know the three lines work. Thank you.

You might also want to investigate saveRDS/readRDS.  Those functions are
similar to save/load, but they only write a single variable and don't
write variable names, so you can do things like

saveRDS(x, "x.rds")
y <- readRDS("x.rds")

to read the value of x directly into y.

Read this carefully. Pay attention to its instructions re: overwriting
existing objects.

Re: Merging RData files

Henrik Bengtsson-5
To expand on what Bert suggests.  Use:

loadToEnv <- function(file, ..., envir = new.env()) {
  base::load(file = file, envir = envir, ...)
}

envA <- loadToEnv("a.RData")
envB <- loadToEnv("b.RData")

and then access the objects in environments envA and envB using
environment access methods, e.g. ls(envir = envA), envA[[name]],
envA$foo, as.list(envA) [careful is large objects], ...
