I have a list of gene that I have put in DAVID analysis. I saved the Kegg pathway, biological process etc results in .csv file. I desire to represent the analysis with dotplot (see image) in R starting with .csv file from DAVID tools. Is there a R script that I can use? Thanks ! enter image description here

Hey alepaolini86,

You may notice that I asked this same question a while ago, and in that question I put the answer with the code, as you can see here.

A: Dotplot for filtered pathways result

note that in my code I used the function facet_grid(Group ~ .) because I wanted to split in groups.

As you can see in my example, that was recently published

S1 =

data <- read.csv("S1.csv", sep =";", header = TRUE, stringsAsFactors = FALSE)
S1<- ggplot(data, aes(x= Group, y=Pathways, size=DEGs, color=FDR, group=Group)) + geom_point(alpha = 0.8) + 

S1 = S1+scale_color_gradient(low = "red2",  high = "mediumblue", space = "Lab", limit = c(0.000000000000000007, 
S1+scale_size(range = c(2, 8))

Best regards,
