R-alpha: Bugs in R-0.50-a1.

Problems in R but not in S:
---------------------------

1) 'unlist' seems to have several other problems than the ones
reported up to now. For instance, 'unlist' can be used on almost any
object in S without much trouble. Eg.:

S> unlist(c(2))

	[1] 2

S>

	---

R> unlist(c(2))

	Segmentation fault (core dumped)
This occurs in R-0.49 and in R-0.50-a1.

Confirmed.

1) The 'R Graphics' window does not have any X class or resource and
therefore cannot be given a default size or geometry. Would it be
possible to give the graphic window a class name so that the size
could be specified in the '.Xdefaults' file?

Yes, that would be nice.

3) Some problems occur when using the help. Eg.,

R> ?"+"

sorry, no help for "Arithmetic".

R>

This occurs in R-0.49 and in R-0.50-a1 and seems to be the case for
any item contained in a help file starting with a capital letter.

The problem is as follows.  The function help() catches the special funs
like "+" etc (more precisely, the arithmetic, comparison, logic and
extract ones) and directly assigns a topic for them.

For "+", the topic is 'Arithmetic".  But the index file has no entry for
that, because (see RHOME/etc/install-help)

***********************************************************************
if [ $lib != 'base' ]
##-- The following is NOT done anymore in 'base':
##-- 1) Each help file should have  ALIAS(..) for  ALL it's objects
##-- 2) The  help file name may differ from _ANY_ object (eg 'Special')
then 
	for file in $FILES
	do
		echo "$file	$file"
	done
fi
***********************************************************************

If that really is the intended usage (Martin?), then e.g. the Arithmetic
file should also have ALIAS(Arithmetic) in it.
