draw_cum_freq {MetaVolcanoR} | R Documentation

## A function to visualize the inverse-cummulative DEG distribution

### Description

This function create a ggplot object with the inverse-cummulative DEG distribution

### Usage

    draw_cum_freq(meta_diffexp, nstud)

### Arguments

`meta_diffexp` | data.frame/data.table containing all the input studies
`nstud` | the number of inputed GEO2R outputs <integer>

### Value

`ggplot2` object

### Examples

    library(dplyr)
    data(diffexplist)
    diffexp <- lapply(diffexplist, function(...) deg_def(..., "pvalue",
               "Log2FC", 0.05, 0))
    diffexp <- rename_col(diffexp, "Symbol")
    meta_diffexp <- Reduce(function(...) merge(..., by = "Symbol", all = TRUE),
               diffexp)
    meta_diffexp %>%
    dplyr::select(dplyr::matches("deg_")) %>%
        data.matrix -> n_deg
    meta_diffexp[['ndeg']] <- rowSums(n_deg^2, na.rm = TRUE)
    gg <- draw_cum_freq(meta_diffexp, length(diffexplist))
    plot(gg)
