Usage
## S3 method for class 'neuralGAM'
autoplot(object, select, xlab = NULL, ylab = NULL, ...)
Arguments
object |
a fitted |
select |
selects the term to be plotted. |
xlab |
A title for the |
ylab |
A title for the |
... |
other graphics parameters to pass on to plotting commands. See details for ggplot2::geom_line options |
Value
