imputeMissingVals: Impute NA values in a traces object

In CCprofiler/CCprofiler: Complex feature detection using SEC protein chromatograms.

Description

Imputes all NA values in a traces object by interpolation.

Usage

imputeMissingVals(traces, method = c("mean", "spline"))

Arguments

traces	Object of class traces.
method	Character string, which interpolation method to use.

Details

Unlike with standard imputation methods, missing values on the borders are linearly extrapolated from the neighboring 2 values. Any imputed value below 0 is set to 0.

Value

Object of class traces with imputed NA values.

Examples

tracesMiss <- findMissingValues(examplePeptideTraces)
tracesImp <- imputeMissingVals(tracesMiss)
View(tracesImp$traces)

# The imputed values can be visualised using the package 'daff'
require(daff)
render_diff(diff_data(examplePeptideTraces$traces, tracesImp$traces))
