Hi I want to obtain a graph like the one in the link (https://i.stack.imgur.com/qfEYh.png) using ggplot2 but I want to order the rows, showing first the ones in which the circle is present for all the three groups (the groups are the .

I wrote this command for my data

ggplot(subset(dataframe, FDR <0.25), aes(x=Type, y=NAME, color=Type)) + geom_point()

where I put the threshold to show the circle only if FDR < 0.25

I want to be shown in the y axis first the NAMES which have the circle present for all 3 conditions.

Thank you in advance for the help

Try this before plotting:

test <- test[order(as.numeric(factor(test$NAME))),]
test$NAME <- factor(test$NAME, levels=rev(unique(test$NAME)))

Thanks, I tried but in this way it orders the NAME just in alphabetic order.
