i'm having trouble saving and loading data frames.
at the end of the data cleaning and coding process, I am trying to
save the objects I want to keep in one data frame and then continue
working using just that data frame. here's what i do:
eggpow<-as.data.frame(cbind( var1, var2, etc.))
save(eggpow, "eggpow1.RData")
later, when I try to load and use it, I do:
eggpow2 <- load("eggpow1.RData")
but eggpow2 has
dim(eggpow2)
NULL
eggpow2
[1] "eggpow"
I expected eggpow2 here to be identical to eggpow at the top. what am
I doing wrong?

I am not quite sure, but I think the problem is in the save line.
If you look at args(save), you will see that it the arguments go like
this: ..., list=, file=). I think R is interpreting you as saying that you
want your data and a string saved, or is interpreting the "eggpow1.Rdata"
as the name of a list.
Try save(eggpow, file="eggpow1.Rdata") and see if that does the trick.

load() doesn't take arguments. Whatever was saved in "eggpow1.Rdata" is
loaded under the name it was saved. Thus:
save(eggpow, file="eggpow1.Rdata")
load("eggpow1.Rdata")
just loads eggpow back into the workspace. If you want to save it as
something else and then load it back:
eggpow1 <- eggpow
save(eggpow1, file = "eggpow1.Rdata")
load("eggpow1.Rdata")
identical(eggpow1, eggpow)

New subject: [gov2001-l] zelig question
Hi,
I want to check if my function for the predicted values for Problem 1c works
properly. So I rerun the model in Zelig:
z.out <-
zelig(MIL~COOP+TARGET+COST+RELAT+COOP.X.TARGET, data=data ,
model="logit")
x.coop1<-
setx(z.out,COOP=1,COOP.X.TARGET=1*median(TARGET),fn=list(numeric=median,
ordered=median))
Error in get(x, envir, mode, inherits) : variable "fn" of mode
"function"
was not found
or just:
x.coop1<- setx(z.out,fn=list(numeric=median,
ordered=median))
Error in get(x, envir, mode, inherits) : variable "fn" of
mode "function"
was not found
What does this error message mean? Something is wrong with the fn=list,
probably, but I don't see what.
Thanks!

Sorry, the installation instructions should have changed too --
there's a bug (at HMDC). Use:
install.packages("Zelig")
That will make sure you're on the most current version (which
works best with R 2.0.0, btw).

Hi there,
Do you have any idea about how R treats NA when we compare values? I know STATA
treats NA as positive infinity. Thanks.

I am not quite sure, but I think the problem is
in the save line.
If you look at args(save), you will see that it the arguments go like
this: ..., list=, file=). I think R is interpreting you as saying that
you
want your data and a string saved, or is interpreting the "eggpow1.Rdata"
as the name of a list.
Try save(eggpow, file="eggpow1.Rdata") and see if that does the trick.

New subject: [gov2001-l] about the treatment of NA
NA is NA. Thus, is.na(x) returns something different from (x ==
Inf).
Stata shouldn't treat them as anything but missing values.
That's a bug in their code.

Subject: [gov2001-l] about the treatment of NA
Hi there,
Do you have any idea about how R treats NA when we compare
values? I know STATA
treats NA as positive infinity. Thanks.
ÒýÓÃ Olivia Lau <olau(a)fas.harvard.edu>du>:
load() doesn't take arguments. Whatever was
saved in
"eggpow1.Rdata" is
loaded under the name it was saved. Thus:
save(eggpow, file="eggpow1.Rdata")
load("eggpow1.Rdata")
just loads eggpow back into the workspace. If you want to
save it as
something else and then load it back:
eggpow1 <- eggpow
save(eggpow1, file = "eggpow1.Rdata")
load("eggpow1.Rdata")
identical(eggpow1, eggpow)
Olivia.

Ben,
Thanks. I had mistyped my code. I actually _had_ done
save(eggpow, file="eggpow1.Rdata")
in the original. So this is not the problem.

I am not quite sure, but I think the problem is
in the
save line.
If you look at args(save), you will see that it the
arguments go like
this: ..., list=, file=). I think R is interpreting you as
saying that
you
want your data and a string saved, or is interpreting the
"eggpow1.Rdata"
as the name of a list.
Try save(eggpow, file="eggpow1.Rdata") and see if that
does the trick.
