plot_detect: Visualize intensities of proteins with missing values

In DEP: Differential Enrichment analysis of Proteomics data

Description

plot_detect generates density and CumSum plots of protein intensities with and without missing values

Usage

plot_detect(se)

Arguments

se	SummarizedExperiment, Data object with missing values.

Value

Density and CumSum plots of intensities of proteins with and without missing values (generated by ggplot).

Examples

# Load example
data <- UbiLength
data <- data[data$Reverse != "+" & data$Potential.contaminant != "+",]
data_unique <- make_unique(data, "Gene.names", "Protein.IDs", delim = ";")

# Make SummarizedExperiment
columns <- grep("LFQ.", colnames(data_unique))
exp_design <- UbiLength_ExpDesign
se <- make_se(data_unique, columns, exp_design)

# Filter
filt <- filter_missval(se, thr = 0)

# Plot intensities of proteins with missing values
plot_detect(filt)
