Hi all

I have not found a package by Googling, but assume there must be at
least one out there.
I need to generate/write sun rise-sun set times (civil twilight) and
moon phase/illumination.

I would like to add a start date and end date along with location
coordinates and have a table generated like below.
This is from a legacy program acquired some 30 years ago and is no
longer available.? This can only generate 1 month at a time (subset
below).? But for a year at a time both historical and for future dates
and locations.

For this legacy program I enter the date and select a location I have
in
a simple TXT location file location with time-zone and X-Y coordinates
and it will generate a month at a time.? this can be dumped to the
clipboard but not written as a TXT or delimited file.

I am hoping there will be an elegant way to do this in R and have the
results written to a file for import into an Access DB.
Tnx for any suggestions? on package(s).

Sample below.
