Description

plots track over map with probability cloud. Can plot only part of the track if dates are specified. Note that you can use it only after obtaining and registering in you current session Google Api Key. For details on the API key check [here](http://ornithologyexchange.org/forums/topic/38315-mapflightrggmap-error).

)

Arguments

Result

FLightR result object obtained from run.particle.filter

dates

either NULL if all twilights should be included or data.frame with first column - start of the period and second end of the period. Each line represents a new period

plot.cloud

Should probability cloud be plotted? If TRUE cloud is estimated by stat_density2d

map.options

options passed to get_map, note that zoom option is defined separately

plot.options

plotting options. Not defined yet!

save.options

options passed to ggsave. Filename should be defined here.

zoom

Zoom for map. If 'auto' FLightR will try to find optimal zoom level by downloading different size maps and checking whether all the points fit the map.

return.ggobj

Should ggobj be returned for subsequent checks and/or replotting

seasonal.colors

if true points of the track will have seasonal colors

seasonal.donut.location

if NULL - no color wheel placed, otherwise select one of 'bottomleft', 'bottomright', 'topleft'

seasonal.donut.proportion

how much of X axis should color wheel occupy. return either NULL or ggplot2 class object

save

should function save results with ggsave?

Value

if 'return.ggobj=TRUE' return ggplot object otherwise returns 'NULL'.

# here we will run only 1e4 partilces for a very short track.

           precision.sd=25, check.outliers=FALSE)

## Not run: 
map.FLightR.ggmap(Result, seasonal.donut.location=NULL, zoom=6, save=FALSE)

## End(Not run) 
# for this short track without variance seasonal donut does not work,
# but for normall track it will.
