Hi All,

My data frame has two columns: Gene names and Z scores. I am using ggplot2 package to make a scatter plot. I was able to create the plot but I don't know how to show only specific gene names on the plot and also how to change the color of the gene names shown.

Here is what I am using:

library(ggplot2) Data<- read.csv("Data.csv", header = TRUE) ggplot(Data, aes(x = Count, y = Z_Score))

Lets say I want to show genenames "Gene1", "Gene2", "Gene3" on the plot and in "red", "blue", "green" respectively.

Many Thanks, Hamid
