R help - Apr 2020 - confidence interval

there is a function called "confbands", which is no longer available
in
software R. It is not "confband" or "confBands", but
"confbands", I need to
use this object to add confidence intervals in my work. Why is this
function not available?
attached is an image that shows how the graph should look, in another image
is the error that appears in the software. "confbands" object not
found. Also attached is an image showing the function functioning normally.
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.

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.

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.
