[R] Sort data and symbol change in Jitter plot (ggplot2)

[Luis Fernando García]

Dear R experts,

First than all I want to thank your expertise and for sharing your
knowledge with the people who are starting.

Recently I have been working on a new plot style (Jitterplot) but have
still some issues when making two basic functions.

First than all I want to change the symbol according to the prey type
(presa) and not the color, I tried making, geom_dotplot(aes(fill = PRESA)
but it did not work

On a second hand I want to sort the plots from the highest to the lowest
value, I tried by using reorder, but it did not work.

Please find attached the dataset and the script.

Thanks in advance!

####script######

the dataset is attached
library(ggplot2)
p=read.table("paratropis.txt",header=T)
attach(p)
ggplot( data = p, aes(y = Tiempo, x = PRESA, reorder(PRESA, Tiempo, mean)))
+ # Move y and x here so than they can be used in stat_*
  geom_dotplot(aes(shape = PRESA),
               binaxis = "y",         # which axis to bin along
               binwidth = 0.1,        # Minimal difference considered
diffeerent
               stackdir = "center"    # Centered
  ) +
  stat_summary(fun.y = mean, fun.ymin = mean, fun.ymax = mean,
               geom = "crossbar", width = 0.5)
