Error in rounding_function when running plot() function #39
Description
Dear maintainer,
Thank you for developing this interesting package. I was following your tutorial using random forest model for classification problem. I faced some problem when I tried using the plot() function:
library("shapper")
library("DALEX")
library("randomForest")
Y_train <- HR$status
x_train <- HR[ , -6]
set.seed(123)
model_rf <- randomForest(x = x_train, y = Y_train, ntree= 50)
p_function <- function(model, data) predict(model, newdata = data, type = "prob")
ive_rf <- individual_variable_effect(model_rf, data = x_train, predict_function = p_function,
new_observation = x_train[1:2,], nsamples = 50)
plot(ive_rf) # error occur when running the plot function
error message:
Error in rounding_function(variable_values[numeric_values], digits) :
non-numeric argument to mathematical function
Could you give me some suggestions on how to fix this issue? Thank you very much for your time!
