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 

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.
