[R-pkg-devel] R CMD INSTALL succeeds while R CMD BUILD fails

[Sam Albers]

Oh you are totally right. And similarly, an .rds file bonks with R CMD build:

$ R CMD build foo.rds
* checking for file 'foo.rds/DESCRIPTION' ... OK
* preparing 'foo.rds':
* checking DESCRIPTION meta-information ... OK
* checking for LF line-endings in source and make files and shell scripts
* checking for empty or unneeded directories
Warning in gzfile(file, "rb") :
  cannot open compressed file 'foo.rds', probable reason 'Permission denied'
Error in gzfile(file, "rb") : cannot open the connection
Execution halted

However this seems like a bug doesn't it? I am able to install a *.rds
or *.rdata package but unable to build it. Seems like a) I should be
able to install and b) these could be added to the list of unavailable
package names. Asking in the context of whether this is worth
reporting as a bug.
