Plot partial dependence

Source: R/plot_pd.R

Plot the partial dependence functions (i.e., marginal effects) for the predictors in a model.

plot_pd(pd)

Arguments

pd

Data frame containing the partial dependence effect as returned by get_pd.

Value

ggplot object showing the partial dependence effect in pd.

Examples

if (FALSE) {
data('mtpl_be')
features <- setdiff(names(mtpl_be), c('id', 'nclaims', 'expo', 'long', 'lat'))
set.seed(12345)
gbm_fit <- gbm::gbm(as.formula(paste('nclaims ~',
                               paste(features, collapse = ' + '))),
                    distribution = 'poisson',
                    data = mtpl_be,
