[Rd] Possible bug in 'relist()' and/or 'as.relistable()'

[Janko Thyson]

Dear list,

I think I just stumbled across a bug in either 'relist()' and/or
'as.relistable()'. It seems that 'pairlists' can only be un- and relisted as
long as they're not nested:

Good:
a <- as.relistable(as.pairlist(list(a=1, b=2)))
a <- unlist(a)
relist(a)# Works

Bad:
a <- as.relistable(as.pairlist(list(a=1, b=2, c=list(c.1=1, c.2=2))))
a <- unlist(a)
relist(a)

The help page didn't say anything about pairlists and I don't know if
they're at all relevant, but I'm using them whenever I want my functions to
recognize a clear 'name-value' structure (e.g. for batch assigning
variables) as opposed to standard list structures.

Cheers,
Janko
