map_locations: View locations on a map

In NTNU-VM/natronbatchupload: a package to facilitate the uploading of datasets to NaTron

Description

map_locations takes the coordinates from up to two location tables and plots them on two maps with different zoom.

Usage

map_locations(data, compare, zoom1 = 11, zoom2 = 8, vertical = FALSE)

Arguments

data	Location table with decimal degree coordinates that you wish to plot. Only DwC terms are recogniced (decimalLatitude and decimalLongitude)
compare	Location table with decimal degree coordinates that you wish to plot alongside the 'data'.
zoom1	Resolution of the smallest scale map. Defaults to 11. Increasing the resolutions also increases computation time.
zoom2	Resolution of the largest scale map. Defaults to 8. Increasing the resolutions also increases computation time.
vertical	Should the plots be arranged vertically (T/F)? Defults to FALSE.

Value

A map (gtable)

Examples

## Not run: 

# Plotting coordinates from one dataset:

decimalLatitude <- c(59.02936, 59.03352, 59.04758) #note that the name must be DwC
decimalLongitude <- c(7.278987, 7.267469, 7.184718)
myData <- data.frame(decimalLatitude, decimalLongitude)
map_locations(data = myData)
map_locations(data = myData, vertical = T)


# Add another location table to compare against:

decimalLatitude2 <- c(59.03347)
decimalLongitude2 <- c(7.268134)
myData2 <- data.frame(decimalLatitude = decimalLatitude2,
                      decimalLongitude = decimalLongitude2)

map_locations(data = myData, compare = myData2)

## End(Not run)
