problem viewing S help files

Tue Jan 8 14:16:32 CET 2002

When I use ESS to request S help files, the information placed in the
*help(obj-name)* buffer does not appear to be correct.  (e.g., below is the
output which appears on typing "C-c C-v sum" within the ESS edit buffer.

How can I obtain correct behavior?

P.S. I'm using Solaris 2.7, ESS version 5.1.19, XEmacs version 21.1

<H1>Sums and Products
</H1>
<H2> DESCRIPTION: </H2>Returns the number that is the sum or product of all
of the elements of
all of the arguments.  Missing values may optionally be removed before
the computations.
<H2> USAGE: </H2>
<PRE>sum(..., na.rm=F)
prod(..., na.rm=F)
</PRE>

<H2> REQUIRED ARGUMENTS: </H2>
<DL>
<DT><B>...</B>
</DT><DD>
numeric or complex objects.
Missing values ( <TT>NA</TT>s) are allowed, but will cause the value
returned
to be  <TT>NA</TT>, unless  <TT>na.rm=TRUE</TT>.
</DD>
</DL>
<H2> OPTIONAL ARGUMENTS: </H2>
<DL>
<DT><B>na.rm=</B>
</DT><DD>
logical flag: should missing values be removed before computation?
This must be specified in the  <TT>na.rm=</TT> form.
</DD>
</DL>
<H2> VALUE: </H2>
<DL>the sum or product of all the elements of all the arguments.
If the total length of all the arguments is 0,  <TT>sum</TT> returns
<TT>0</TT>
and  <TT>prod</TT> returns  <TT>1</TT>.
</DL>
<H2>DETAILS:</H2>
 <P>
These functions are members of the  <TT>Summary</TT> group of generic
functions.
</P>

<H2>  WARNING: </H2>
 <P>

The  <TT>sum</TT> function performs integer arithmetic if all
of the numbers are considered integers.
If overflow occurs, integer arithmetic "wraps around" rather than producing
an error or an  <TT>NA</TT>.  For example,
<TT>sum(as.integer(c(2147483647,34)))</TT>
returns  <TT>-2147483615</TT>.
</P>
