Re: [R] write.table equivalent for lists?

2011-01-10 Thread Ivan Calandra 

Hi,

If I understood you correctly, you can use saveObject()/loadObject() 
from package R.utils, like this:


library(R.utils)
saveObject(x, x.Rbin)
rm(x)
y - loadObject(x.Rbin)

HTH,
Ivan

Hi

I am writing simulations in R, and quite regularly, I have to save lists
and objects to HDD and load it later again.

So I am wondering: why is there no function to write lists (and S3, S4
objects) onto HDD WITHOUT keeping the name? What I mean is:

For data.frames I can use

x- data.frame(x = runif(10))
write.table(x, x.txt)
rm(x)

y- read.table(x.txt)

to load it into y.

But for lists and S3, S4 objects, I have to use save() and load():

x- list(x=1:10, y=letters(1:10))
save(x, file=x.rdata)
rm(x)

load(x.rdata) #1
y- x  #2
rm(x)   #3

to load it into y.
I don't mind the binary of save - what I am really missing is a command
which combines lines #1, #2 and #3.

I know - I could write my own

save.list- function(x, file) {
   save(s, file=file)
}

load.list- function(file) {
   load(file)
   return(x)
}

which I could then use as:

x- list(x=1:10, y=letters(1:10))
save.list(x, test.rdata)

rm(x)

y- load.list(test.rdata)

but: why is there not such a function? Am I missing something here?

Cheers,

Rainer

Well, I suspect that Rainer has been on this list long

 Because no has convinced R-Core to implement it!

Henrik write excellent code, maintains it well, and
responds quickly. Can't ask for much more.

As to putting this into pkg:base or pkg:utils, Ivan,
have a look at the code of R.utils::loadObject; it's not
quite trivial.

Re: [R] write.table equivalent for lists?

2011-01-10 Thread William Dunlap 
serialize() and unserialize() in the base package
should do the job also and are usually quite a bit
faster than dput() and dget().  However, the format
is not easily read by other programs.

  But for lists and S3, S4 objects, I have to use save() and load():
  
  x - list(x=1:10, y=letters(1:10))
  save(x, file=x.rdata)
  rm(x)
  
  load(x.rdata) #1
  y - x  #2
  rm(x)   #3
  
  to load it into y.
  I don't mind the binary of save - what I am really missing 
 is a command
  which combines lines #1, #2 and #3.
  
  I know - I could write my own
  
  save.list - function(x, file) {
save(s, file=file)
  }
  
  load.list - function(file) {
load(file)
return(x)
  }
  
  which I could then use as:
  
  x - list(x=1:10, y=letters(1:10))
  save.list(x, test.rdata)
  
  rm(x)
  
  y - load.list(test.rdata)
  
  but: why is there not such a function? Am I missing something here?
  
  Cheers,
  
  Rainer
