Hi Martin,
Sounds good. Are there any plans to support the xz compression for
package source tarballs?
What makes you think it is not supported?
R CMD INSTALL happily installs .tar.xz files, and the name is not used
to detect compression so .tar.gz fil
It's per design:
?names

The name '""' is special: it is used to
indicate that there is no
name associated with an element of a (atomic
or generic) vector.
Subscripting by '""' will match nothing (not even
elements which
have no name).

Hi,
I notice that one can assign a variable to an R list by using an empty
string key but one cannot get that variable back from the list by using the
empty string key:
```r
l <- list()
l[[""]] <- "An empty string as list key"
names(l)
l[[""]] # Returns a `NULL`
l[[names(l) == ""]] # Returns firs
