In which even the functions of the object appear.
There was no attached image or images. That is because you have not
carefully read the information provided here:
https://stat.ethz.ch/mailman/listinfo/r-help and in the Posting Guide.
Alex replied to me and failed to include the mailing list. He again
attached images. One of these images showed a fragment of a console
session where a `confbands` function was displayed in part. It had a
parameter of newdata and used the function `mydeltaMethod`, so I did a
google search on "confbands newdata mdeltamethod" and found this page of
code:
http://arsilva.weebly.com/uploads/2/1/0/0/21008856/function_confbands.r
It matches the image exactly, so I think I have identified the missing
function.
Alex: You still do need to read the Posting Guide and the list Info
page. The next respondent on rhelp may not be as forgiving of your sins
against protocol.

R is composed of packages. You need to know which package the
"confbands" function came from before we can identify the cause of its
absence.
It could be that you have not installed or loaded the package into
your session. Or it could be that the author of the package in which
it used to be made available has not maintained it on CRAN. Or perhaps
it was never on CRAN and was instead on some blog or class assignment
where it was defined upstream and you failed to notice it. All these
situations have been seen on Rhelp posted by persons claiming that a
function has gone missing.
