Plot position frequency

Plots the frequency of coverage of protein sequence.

plot_position_frequency(
  dat,
  protein = dat[["Protein"]][1],
  chosen_state = dat[["State"]][1]
)

Arguments

dat	data as imported by the read_hdx function
protein	protein to be included in plot
chosen_state	sequence states to be included in plot

Value

a ggplot object.

Details

The function plot_position_frequency plots a histogram of the coverage frequency based on experimental data. The aim of this plot is to see how many times each position of the sequence was covered (by different peptides).

Examples

# load example data
dat <- read_hdx(system.file(package = "HaDeX", 
                            "HaDeX/data/KD_180110_CD160_HVEM.csv"))
                            
# function call with default parameters
plot_position_frequency(dat)

# function call with explicit parameters
plot_position_frequency(dat, chosen_state = "CD160_HVEM")
