Thanks; your response is very helpful. This message has some remarks
on my questions relative to the developer docs, one additional
question, and some documentation comments.
I'm really glad to hear you plan to revise the exception/condition
docs. since I found the existing ones a bit murky.

Qualitatively I believe so. Names were changed and some details were
changed to better integrate with existing paractice and internals, and
the hook mechanisms used for experimenting are either no longer
available or will be removed before long. Sorting these things out is

Thanks Luke (and Brian). The note is entitled "A Prototype of a
Condition System for R" - can we assume the actual implementation is
as described?
Thanks,

'format.pval' has a major limitation in its implementation for example
suppose a person had a vector like 'a' and the error being ±0.001.

The person wants to have the 'format.pval' output with 2 digits always

Currently, as far as I can see, both input and output fles must be
supplied in the 'tests' directory (the input in a '.R' file, and the
output in a corresponding '.Rout.save' file.) Often, the '.R' file is
redundant, as it could be reconstructed by simply stripping the commands
out of the '.Ro

Hi,
I noticed that if a column is named "end" in a data frame (table.df
below), it leads to errors when trying to sqlSave()'it to a postgresql
