Have you tried Hadley's devtools package? It probably has the best tools
for auto-reloading packages. On occasion it will jam on me and I have to
restart R, but most times load_all("Hello", recompile=T) should do what you
want.
I tried your suggestion (using also 'export_all = FALSE') but I got the warning message Loading Hello Warning in setup_ns_exports(pkg, export_all) : Objects listed as exports, but not present in namespace: .package, helloRcpp1, helloCpp1, helloC1, helloF1 and the successive error message Error in print(helloF1(ny)) : could not find function "helloF1" (where "helloF1" is one of the functions I'm testing). Note that I exported in the NAMESPACE file all functions listed in above warning message. Thank you for your help Fabrizio Cipollini

From time to time, I use R to develop my own packages.
For testing purposes, I need frequently
***to detach the previous version and attach a more recent built without
leaving the R session***.
I'm able to do this with the command
detach(name = "Hello", unload = TRUE, force = TRUE)
if I include in the source package a
zzz.R file
with the function
.onUnload <- function(libpath = NULL)
{
library.dynam.unload("Hello", libpath)
}
("Hello" is the name of the package I used for testing)
However, if "Hello" links and imports "Rcpp" (and an import(Rcpp) directive
is included in NAMESPACE) all this stuff does not work, in the sense that
even detaching and building a new version of "Hello", the previous one is
attached.
On the other side, if I quit R and I open another session, the last version
of "Hello" is attached successfully.
