R Documentation

Plot protein numbers

Description

plot_numbers generates a barplot of the number of identified proteins per sample.

Usage

plot_numbers(se, plot = TRUE)

Arguments

`se`	SummarizedExperiment, Data object for which to plot protein numbers (output from `make_se()` or `make_se_parse()`).
`plot`	Logical(1), If `TRUE` (default) the barplot is produced. Otherwise (if `FALSE`), the data which the barplot is based on are returned.

Value

Barplot of the number of identified proteins per sample (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 and plot numbers
filt <- filter_missval(se, thr = 0)
plot_numbers(filt)
