surfacePlot: Generate a contour or image
In MattForsyth/oceanchemistry: Ocean Chemistry Analysis

Description Usage Arguments See Also Examples

This function generates a contour plot or an images (surface plot). The most frequent application of this function is surface nutrient data. surfacePlot can handle multiple measurements or variables at once. You can choose between a surface plot, a contour plot, or both. The surface plot uses a colour-blind-friendly palette taken from the oce package.

1 2	surfacePlot(depth_column, latitude, longitude, measurements, plot_depth, surface = T, contour = F)

`depth_column`	Depth (or pressure) values.
`latitude`	Latitude coordinates.
`longitude`	Longitude coordinates.
`measurements`	The measurements to plot. If you have multiple variables they should be presented in columns or a dataframe.
`plot_depth`	The lower limit of the surface plot. Currently this function will plot between the surface and whatever depth is input.
`surface`	Do you want to make a surface plot?
`contour`	Do you want to make a contour plot?

This function relies on the interpBarnes function from the oce package: https://cran.r-project.org/web/packages/oce/oce.pdf.
