Volcano plot of combined results

volcano_plot returns a volcano plot of the combined results on each metabolite obtained by compute_amanida function

volcano_plot(mets, cutoff = NULL)

Arguments

• mets: an S4 METAtables object
• cutoff: values for p-value and fold-change significance

Returns

plot of results

Details

Results are presented as -log10 for p-value and log2 for fold-change. Values over the cut off are labeled. If not cutoff is provided will be used alpha 0.05 for p-value and 1.5 for logarithmic fold-change.

Examples

## Not run:

   data("sample_data")
   
   amanida_result <- compute_amanida(sample_data)
   volcano_plot(amanida_result)
## End(Not run)
