In AnnaMagdalena/Ocgrtools: Tools for visualizing oceanographic data

knitr::opts_chunk$set(echo = TRUE)

package developed as a part of STATS545 coursework

Ocgrtools lets you to create speady plots of ocean property depth profiles and contains a dataset to go with it.

The problem

One of the most important visualizations of oceanographic data is the use of depth profiles. Depth profiles are plotted with depth along the vertical axis (y-axis) where seasurface represents 0m and is plotted at the top axis and deepest waters (eg. 2000m) are plotted at the bottom of y-axis. The range on the horizontal axis (x-axis) represents the range in the ocean property being plotted. Using any plot functions, be it R base or ggplot renders a graph where depths representing 0m occur at the bottom of the y-axis and the deepest depths occur at the top of the y-axis, which is counterinuitive to visualization of properties with depth. As such each time these ocean properties are plotted the "plotter" is required to reverse the y-axis. The pplot (property plot) function in this packages allows to create such plots more readily

Installation

 devtools::install_github("AnnaMagdalena/Ocgrtools")

Demo

Use the included data to learn about chemistry of the North Pacific Ocean. Read some more about this dataset in the vignette

library(Ocgrtools)
dat <- CuLineP201127
head(dat)

Get this:

library(ggplot2)
pplot(dat,"dCu_kg","depth")

Versus this:

ggplot(dat,aes(x=dCu_kg,y=depth))+geom_point(aes(colour=stn),size=3)
