Dear R community,
With an advantage of being "NEW" to R, I would like to post a very basic
query here,
I am in need of representing gene expression data which ranges from -0.09 to
+4, on plot "segment". please find below the data df, the expression values
are in df[,2]. kindly help me with the code, so that I can represent the
values with a clear color gradient (something like -0.09 to 0 as red
gradient and 0 to +4 as green gradient)
location value
