get_r_squared: R Squared Metrics for Predictions

Description

A function to return R^2 metrics for predictions vs actual values. Works well when piped to straight from get_predictions().

Usage

get_r_squared(predictions, biomarker_values, model = "", threshold = 10)

Arguments

predictions

(list) A list with two elements, 'predictions' and 'panel_lengths', as produced by the function get_predictions().

biomarker_values

(dataframe) A dataframe with two columns, 'Tumor_Sample_Barcode' and a column with the name of the biomarker in question containing values.

model

(character) The name of the model type producing these predictions.

threshold

(numeric) Unusued in this function: present for calls to get_stats().

Value

A dataframe with 5 columns:

• panel_length: the length of each panel.

• model: the model that produced the predictions.

• biomarker: the name of the biomarker in question.

• stat: the R squared values for each panel.

• metric: a constant character "R" for R squared.

Examples

# NOT RUN {
example_r <- get_r_squared(predictions = get_predictions(example_refit_panel, new_data =
  example_tables$val), biomarker_values = example_tmb_tables$val, model = "Refitted T")
# }
