Plots GLM regression residuals vs fitted values for a CpG site

Description

Plots GLM regression residuals vs fitted values for a CpG site

Usage

ewaff.glm.residuals.plot(variable.of.interest, data, methylation, title)

Arguments

variable.of.interest	Name in colnames(data) for the variable of interest.
data	Data frame containing all variables.
methylation	Vector of methylation levels.
title	Title of the plot.
ggplot	object showing the scatterplot of fitted values vs residuals for the model methylation ~ variable + covariates.

Examples

methylation <- ... ## methylation matrix
data <- ... ## variable of interest (smoking) and covariates
obj <- ewaff.sites(methylation ~ smoking + ., methylation, data)
cpg <- "cg05575921"
p <- ewaff.glm.residuals.plot("smoking", as.data.frame(object$design), methylation[cpg,], cpg)
print(p)
