Prepare a table for volcano plotting

Keeps just the FDR and logFC columns (optionally only significant rows), preserving row names so genes can be labelled later.

Usage

clean_volcano_data(input.data, sig.only = TRUE)

Arguments

input.data

Data frame with FDR and logFC columns.

sig.only

If TRUE, keep only rows with FDR < 0.05.

Value

A data frame with FDR and logFC.

Examples

df <- data.frame(FDR = c(0.01, 0.2), logFC = c(2, -0.3),
                 row.names = c("A", "B"))
clean_volcano_data(df, sig.only = TRUE)
#>    FDR logFC
#> A 0.01     2
