volcanoplots with different colors for up/down regulated genes

Hi,

I would appreciate it if anyone could direct me on how to give different colors for the up and down-regulated genes using the R Bioconductor package enhancedvolcano.

Just as indicated in the following link.

Thanks!

Hey,

This can be achieved via customised coding or EnhancedVolcano. Please take a look at the vignette, where there is a dedicated section for this (see Section 4.9): http://bioconductor.org/packages/devel/bioc/vignettes/EnhancedVolcano/inst/doc/EnhancedVolcano.html

Thank you so much! However, when I am changing the labels(high, low, mid) by my keywords, let say "up," "down," and "none," those genes pop up in the plot are not coming just the dot points. AD

To receive help, you will have to share the code that you are running, and [preferably] a fully reproducible sample dataset. Thanks.
