Get Depth by Year

Description

Get depth of positive and empty tows by year plotted in a histogram.

Usage

get_depthbin(df, vline = 366)

Arguments

df	A data frame from the NWFSC warehouse.
vline	The x-axis location of the vertical line. The default is to include a line at 366 m because of the change in sampled depths in the Triennial Survey. A value of vline = NULL will remove the line from the plot.

Value

A ggplot object.
