|---|---|
| output_name | (char) Name for the output file (don't forget the |
| lfc_upper | (numeric) log2fc upper threshold (positive value) |
| lfc_lower | (numeric) log2fc lower threshold (negative value) |
| whatPvalue | (char) |
| FDR | (numeric) False Discovery Rate threshold |
(logical) Option to generate pdf format. Default: |
|
| decimal_threshold | (numeric) Decimal threshold for the pvalue. Default: 16 (10^-16) |
