[R] FD package_dbFD error

[Bert Gunter]

I think you would more likely find the help you seek on the r-sig-ecology
list rather than here.

Also, do note per the posting guide linked below:

"For questions about functions in standard packages distributed with R (see
the FAQ Add-on packages in R
<https://cran.r-project.org/doc/FAQ/R-FAQ.html#Add-on-packages-in-R>), ask
questions on R-help.
If the question relates to a *contributed package* , e.g., one downloaded
from CRAN, try contacting the package maintainer first [who you can find
via ?maintainer]. You can also use find("functionname") and
packageDescription("packagename") to find this information. *Only* send
such questions to R-help or R-devel if you get no reply or need further
assistance. This applies to both requests for help and to bug reports."
