point size

You could add size = log10_P to the aes() inside geom_point().
Untested code below.
See also http://ggplot2.tidyverse.org/reference/geom_point.html

ggplot(mydata,  aes(x = X,  y = log10_P)) +
  theme_bw() +
  theme(panel.border=element_blank(), legend.position="top",
 axis.text=element_text(size = 8)) +
  geom_point(aes(color = Traits, size = log10_P))

Hi all;

I am running the following ggplot codes. Runs well. However, I need to
reflect the numeric values of the log10_P to the point size in the graph.

Your help highly appreciated,

Regards,
Greg


p <- ggplot(mydata,  aes(x = X,  y = log10_P)) +
  theme_bw() +theme(panel.border=element_blank())
  + theme(legend.position="top",  axis.text=element_text(size = 8))
  (p1 <- p + geom_point(aes(color = Traits)
