get_pdp_predictions_seq: get predictions compatible with the partial dependence...

In easyalluvial: Generate Alluvial Plots with a Single Line of Code

get predictions compatible with the partial dependence plotting method, sequential variant that only works for numeric predictions.

Description

has been replaced by pdp_predictions which can be paralelized and also handles factor predictions. It is still used to test results.

Usage

get_pdp_predictions_seq(df, imp, m, degree = 4, bins = 5, .f_predict = predict)

Arguments

df	dataframe, training data
imp	dataframe, with not more then two columns one of them numeric containing importance measures and one character or factor column containing corresponding variable names as found in training data.
m	model object
degree	integer, number of top important variables to select. For plotting more than 4 will result in two many flows and the alluvial plot will not be very readable, Default: 4
bins	integer, number of bins for numeric variables, increasing this number might result in too many flows, Default: 5
.f_predict	corresponding model predict() function. Needs to accept 'm' as the first parameter and use the 'newdata' parameter. Supply a wrapper for predict functions with x-y syntax. For parallel processing the predict method of object classes will not always get imported correctly to the worker environment. We can pass the correct predict method via this parameter for example randomForest:::predict.randomForest. Note that a lot of modeling packages do not export the predict method explicitly and it can only be found using :::.
