prepf: Generate an object for kftrack or kfsst (or ukfsst)...
In galuardi/analyzepsat: Microwave Telemtry PSAT analysis

Description Usage Arguments Value Author(s) See Also Examples

This function takes an object created by MWTextract and returns a data frame with 7 columns suitable for kf estimation. This also sets some limits on where in the world the fish may have gone. These limits are meant to be extremely broad and exist to filter only the most egregiously erroneous light measurements.

1	prepf(tag, xmin = 100, xmax = 0, ymin = 10, ymax = 55, keepall = F)

`tag`	object returned from MWTextract
`xmin`	Southern longitude cutoff
`xmax`	Northern longitude cutoff
`ymin`	Southern latitude cutoff
`ymax`	Northern latitude cutoff
`keepall`	If you do not wish to use these cutoffs, keepall = T. Default is keepall = F

Dataframe with 7 columns: Day, Month, Year, Longitude, Latitude, Max Daily Depth, Max Daily Ambient Temperature
