Interpolated contour plot of particular variable

Creates interpolated contour plot, can be used as a background for ROI or tow yo information

vpr_plot_contour(
  data,
  var,
  dup = "mean",
  method = "interp",
  labels = TRUE,
  bw = 1,
  cmo
)

Arguments

data: data frame needs to include time_hr, depth, and variable of choice (var)
var: variable in dataframe which will be interpolated and plotted
dup: if method == 'interp'. Method of handling duplicates in interpolation, passed to interp function (options: 'mean', 'strip', 'error')
method: Specifies interpolation method, options are 'interp' or 'oce', oce uses slightly different method (oce is least error prone)
labels: logical value indicating whether or not to plot contour labels
bw: bin width defining interval at which contours are labelled
cmo: name of a cmocean plotting theme, see ?cmocean for more information
