Description

Make a surface plot

Usage

surfaceplot(tab, coords_name, var_name, h = 8, col.pal, mark_points = FALSE)

Value

a ggplot object containing the surface plot

Arguments

tab

a data-frame containing spatial co-ordinates and the variable to plot

coords_name

name of the two columns that contains the co-ordinates of the points

var_name

name of the column containing the variable to be plotted

h

integer; (optional) controls smoothness of the spatial interpolation as appearing in the MBA::mba.surf() function. Default is 8.

Examples

data(simGaussian)
plot1 <- surfaceplot(simGaussian, coords_name = c("s1", "s2"),
                     var_name = "z_true")
plot1

# try your favourite color palette
col.br <- colorRampPalette(c("blue", "white", "red"))
col.br.pal <- col.br(100)
plot2 <- surfaceplot(simGaussian, coords_name = c("s1", "s2"),
                     var_name = "z_true", col.pal = col.br.pal)
