Subject: [R] Sort data and symbol change in Jitter plot (ggplot2)
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)
Do not use attach, it only confuses things.
firs reorder your factor
p$PRESA - reorder(p$PRESA, p$Tiempo, mean)
then use geom point to get different shapes.
pl-ggplot( data = p, aes(y = Tiempo, x = PRESA, shape=PRESA))
pl + geom_point()+ geom_dotplot(binaxis = y, binwidth = 0.1, stackdir =
center) +
stat_summary(fun.y = mean, fun.ymin = mean, fun.ymax = mean, geom =
crossbar, width = 0.5)
Is this what you wanted?
Cheers
Petr
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)
