getSpatialMap_comb function

Combine maps together

getSpatialMap_comb(
  ...,
  list = NULL,
  nrow = 1,
  x = "",
  y = "",
  title = "",
  output = FALSE
)

Arguments

• ...: different maps generated by getSpatialMap(, output = 'ggplot'), see details.
• list: If input is a list containing different ggplot data, use list = inputlist.
• nrow: A number showing the number of rows.
• x: A string of x axis name.
• y: A string of y axis name.
• title: A string of the title.
• output: A boolean, if chosen TRUE, the output will be given.

Returns

A combined map.

Details

For getSpatialMap_comb, the maps to be compared should be with same size and resolution, in other words, they should be fully overlapped by each other.

If they have different resolutions, use interpGridData{ecomsUDG.Raccess} to interpolate.

Examples

## Not run:

data(tgridData)# the result of \code{\link{loadNcdf}}
#The output should be 'ggplot'
a1 <- getSpatialMap(tgridData, method = 'summer', output = 'ggplot', name = 'a1')
a2 <- getSpatialMap(tgridData, method = 'winter', output = 'ggplot', name = 'a2')
a3 <- getSpatialMap(tgridData, method = 'mean', output = 'ggplot', name = 'a3')
a4 <- getSpatialMap(tgridData, method = 'max', output = 'ggplot', name = 'a4')
getSpatialMap_comb(a1, a2)

# or you can put them into a list.
getSpatialMap_comb(list = list(a1, a2), nrow = 2)
## End(Not run)
