R help - Apr 2012 - Package seems to be present but library don't find it

Hi,

I try to make my first package? The HelloWorld.R file is:
#### HelloWorld.R ####
#' showHello est une fonction R permettant d'afficher le message
#' "Hello World!" sur la console.
#' @title la fonction showHello()

showHello <-function(){
cat("Hello World!\n")
}

I use the following procedure to get the tar:

# set the working directory where the file is located
 > setwd("...")

 >
package.skeleton("HelloWorld",code_files=c("HelloWorld.R"))

# to generate .rd files
 > library("roxygen2")
 > roxygenize("HelloWorld",copy.package=FALSE)

 > system("R CMD build '/Users/marcgirondot/Documents/Espace de
travail
R/Phenology/Source fit/Essai_package/HelloWorld'")
* checking for file ?/Users/marcgirondot/Documents/Espace de travail 
R/Phenology/Source fit/Essai_package/HelloWorld/DESCRIPTION? ... OK
* preparing ?HelloWorld?:
* checking DESCRIPTION meta-information ... OK
* checking for LF line-endings in source and make files
* checking for empty or unneeded directories
Removed empty directory ?HelloWorld/inst?
* building ?HelloWorld_1.0.tar.gz?


 > install.packages("/Users/marcgirondot/Documents/Espace\ de\ travail\ 
R/Phenology/Source\ fit/Essai_package/HelloWorld_1.0.tar.gz", repos = NULL)
Installing package(s) into 
?/Library/Frameworks/R.framework/Versions/2.14/Resources/library?
(as ?lib? is unspecified)

 > library("HelloWorld")
Erreur dans library("HelloWorld") :
?HelloWorld? n'est pas un nom correct de package install?

Whereas the Helloworld folder is available in the library folder with 
other packages
/Library/Frameworks/R.framework/Versions/2.14/Resources/library/HelloWorld

In case someone has the competence to check, the file is here:

setwd("~")

download.file("http://www.ese.u-psud.fr/epc/conservation/r-scripts/HelloWorld_1.0.tar.gz",
"HelloWorld_1.0.tar.gz")

install.packages("HelloWorld_1.0.tar.gz", repos = NULL)

Thanks a lot

Marc
