I used svn to copy the current version of Ecdat from Rforge to my PC
C:\temp\packages>svn checkout svn://r-forge.r-project.org/svnroot/ecdat/
then fired up R to look at the rda files in it.
> setwd("c:/temp/packages/Ecdat/ecdat/pkg/data")
> read.dcf("../DESCRIPTION")[, c("Package","Version")]
Package Version
"Ecdat" "0.2-3"
> dir.rda <- function(rdaFile) { e <- new.env() ; load(rdaFile, envir=e) ;
> objects(e, all=TRUE)}
> dir.rda("VietNamH.rda")
[1] "MedExp"
> rdas <- dir(pattern="\\.rda$")
> names(rdas) <- rdas
> z <- lapply(rdas, dir.rda)
> tab <- table(unlist(z))
> tab[tab>1]
Hstarts MedExp
3 2
> z[sapply(z, function(zi)"Hstarts" %in% zi)]
$Hstarts.rda
[1] "Hstarts"
$Intratesm.rda
[1] "Hstarts"
$Intratesq.rda
[1] "Hstarts"
> z[sapply(z, function(zi)"MedExp" %in% zi)]
$MedExp.rda
[1] "MedExp"
$VietNamH.rda
[1] "MedExp"
It looks some files don't contain what their names suggest:
> dir.rda("VietNamH.rda")
[1] "MedExp"
The two versions of MedExp are quite different:
> load("VietNamH.rda", envViet <- new.env(parent=emptyenv()))
> load("MedExp.rda", envMed <- new.env(parent=emptyenv()))
> objects(envViet)
[1] "MedExp"
> objects(envMed)
[1] "MedExp"
> all.equal(envViet$MedExp, envMed$MedExp)
[1] "Names: 11 string mismatches"
[2] "Length mismatch: comparison on first 11 components"
[3] "Component 1: 'current' is not a factor"
...
[18] "Component 10: Numeric: lengths (5999, 5574) differ"
[19] "Component 11: 'current' is not a factor"
