estimate_missing_value: Estimate the missing entries in a response data

In Dahaniel/DoOR.functions: Integrating Heterogeneous Odorant Response Data into a Common Response Model: A DoOR to the Complete Olfactome

Estimate the missing entries in a response data

Description

Estimate the missing entries in a response data

Usage

estimate_missing_value(data, nodor, method = "PC")

Arguments

data	a data frame or matrix, contaning the consensus response values
nodor	a numeric value, specifying the number of the selected odors
method	character string, specifying the method ("PC" (Pearson's coefficient) and "Knn" (k nearest neighbors)) for estimation, the default is "PC".

Details

A wrapper programe for using Pearson Correlation or k-nearest neighbors to estimate the missing entries in a response matrix.

# pick an example subset
subset <- door_response_matrix[1:100, 11:30]

# estimate missing values
est.data <- estimate_missing_value(data = subset, nodor = 6)
