Hi,
With R version 2.13.0 alpha (2011-03-24 r55004), 'R CMD check' will
produce the following output on some packages:
* checking Rd metadata ... WARNING
Error in is.function(FUN) : 'FUN' is missing
Calls: print ... format.check_Rd_metadata -> unlist -> lapply ->
match.fun
Execution halted
This is happening on packages that contain duplicated \name or \alias
tags in their Rd files. 'R CMD check' is able to detect this situation
but is not able to display the warning message correctly because of
a typo in the tools:::format.check_Rd_metadata() function:
format.check_Rd_metadata<-
function(x, ...)
{
c(character(),
if(length(bad<- x$files_with_duplicated_name)) {
unlist(lapply(names(bad)),
function(nm) {
c(gettextf("Rd files with duplicated name '%s':",
nm),
.pretty_format(bad[[nm]]))
})
},
if(length(bad<- x$files_with_duplicated_aliases)) {
unlist(lapply(names(bad)),
function(nm) {
c(gettextf("Rd files with duplicated alias '%s':",
nm),
.pretty_format(bad[[nm]]))
})
})
}
Note the closing parentesis for the lapply() calls? Looks like it
was intended to be something like:
unlist(lapply(names(bad),
function(nm) {
c(gettextf("Rd files with duplicated name
'%s':",
nm),
.pretty_format(bad[[nm]]))
}))
Cheers,
H.
Thanks, will fix.
