I'm trying to change the color of my data in a Scatter Plot. I have 5 columns (only 3 with values for my Plot) with 264.000 rows, this is my dataframe:
ID1 ID2 dN dS t
QJY77946 NP_073551 0.0241 0.1402 0.1479
QJY77954 NP_073551 0.0119 0.0912 0.0870
QJY77954 QJY77946 0.0119 0.0439 0.0566
My Scatter Plot when I make Column dN vs dS is this:

My question: How I can change the color for points in each column (one color for column dN, the other for the column dS...)??
I´m using ggplot2 and tidyverse libraries in RStudio, this is my code for Scatter Plot:
ggplot(aes(x = dN, y = t)) +
geom_point(size = 0.2) +
labs(title = "Pairwise Comparison S Protein",
subtitle = "dS vs dN with YN00",
x = "dS rate",
y = "dN rate") +
theme_bw() +
theme(axis.title = element_text())
Any idea or help is welcome! Thank!
