Hello,
What about this?
straightline <- function(x, slope, intercept) slope*x + intercept
p <- ggplot(data = trainset, aes(x=x, y=y, color=z)) +
geom_point() +
geom_ribbon(aes(ymin = straightline(x, slope_1, intercept_1 + 1/w[2]),
ymax = straightline(x, slope_1, intercept
min = slope_1*x + intercept_1 - 1/w[2],
> ymax = slope_1*x + intercept_1 + 1/w[2], fill = "grey70", alpha=0.1))

Hello,
I am running SVM and showing the results with ggplot2. The results
include the decision boundaries, which are two dashed lines parallel
to a solid line. I would like to remove the dashed lines and use a
shaded area instead. How can I do that?
Here is the code I wrote..
