- Year
A vector of years for the data.

- res
A vector of residuals.

- res_sd
A vector of year specific standard deviation for

`res`

.- res_sd_CI
The confidence interval for the error bars based for

`res_sd`

.- res_upper
A vector of year-specific upper bounds for the error bars of the residual (in lieu of argument

`res_CV`

).- res_lower
A vector of year-specific lower bounds for the error bars of the residual (in lieu of argument

`res_CV`

).- res_ind_blue
Indices of

`obs`

for which the plotted residuals and error bars will be blue.- draw_zero
Indicates whether a horizontal line should be drawn at zero.

- zero_linetype
Passes argument

`lty`

(e.g. solid line = 1, dotted = 2) to`draw_zero`

.- label
Character string that describes the data to label the y-axis.

A plot of model residuals by year (optionally, with error bars).
