f_model_data_grid: generates a data grid based on a formula

In erblast/oetteR: Collection of personal R functions

Description

the range of one specified variable is expanded, while all other variables are set to the most common values. Similar to modelr::data_grid but it can deal with factors.

Usage

f_model_data_grid(col_var, data_ls, formula, n = 500,
  set_manual = list())

Arguments

col_var	character vector, denoting variable that should be expanded
data_ls	data_ls object generated by f_clean_data(), or a named list list( data = <dataframe>, numericals = < vector with column names of numerical columns>)
formula	formula
n	integer, length of grid, datapoints in between range of col_var
set_manual	named list, set some variables manually instead of defaulting to median or most common factor. !! Values need to be of the same variable type as in the original data.

Value

dataframe

Examples

data_ls = f_clean_data(mtcars)
formula = disp~cyl+mpg+hp
f_model_data_grid( 'mpg', data_ls, formula,  10 )
f_model_data_grid( 'mpg', data_ls, formula,  10 , set_manual = list( cyl = min(data_ls$data$cyl) ) )
