Plots for MS analyses

ms_boxplot shows boxplots of different MS expression data values. ms_mean_var shows mean-sd plots for the VSN data values to analyze the mean-variance relationship.

Usage

ms_boxplot(x, width = 8, height = 10, path = NULL)

ms_mean_var(x, g, title = NULL, width = 8, height = 10, path = NULL)

Arguments

x

data object returned by ms_process

width

width of plot

height

height of plot

path

file path to save figure. Device is pdf.

g

vector of treatment groups

title

vector of titles for each g

Value

Both functions return a pdf saved to the file location specified by path. ms_boxplot shows three boxplots of expression values: raw data values, log2 and vsn transformed values. ms_mean_var shows the vsn transformed values and mean-sd plots for each treatment group.
