Plot the missing values vs signal:noise

Missing values are more frequent with low signal:noise (S:N). This function visualises this relationship to aid selection of thresholds for minimal S:N filtering

plot_missing_SN(obj, sn_column = "Average.Reporter.SN", bins = 20)

Arguments

obj

MSnSet containing PSM level TMT intensities

sn_column

character column name for signal:noise values

bins

numeric Number of bins to plot

Value

ggplot stacked bar plot to show S:N vs # missing values
