Hello,
I think the function find_x_from_profile below does what you want.
I have used the data set in the first example of ?readARFF, the built-in
and all-present data set iris.
The function returns a one line data.frame whose column names are "x"
and "y". Pass the y-axis value in argument
I am sorry for that.
I used
library(farff)
library(mlr3learners)
library(mlr3filters)
library(mlr3extralearners)
library(mlr3)
library(DALEX)
library(DALEXtra)
data = readARFF("ant.arff")
index= sample(1:nrow(data), 0.7*nrow(data))
train= data[index,]
test= data[-index,]

Hello,
If you cannot determine the exact value of y for given x, then isn't
your problem how to determine an approximate value of y? Once you have
it, it's easy to plot it.
With newdata = data.frame(x = 75, y = ???),
ggplot(mydata, mapping = aes(x, y)) +
geom_point(color = "black") +
