[R] Date order question

[Ebert,Timothy Aaron]

1) Your "dates" are not being processed as dates. They are strings.
2) As written your date "01-01" comes first because year is not specified and January comes before December.
3) A library statement is missing. I tried running the program and theme_cowplot() was not found.

As you are plotting strings, you could put a space character in front of the December dates so that they are first. 
date<-c(" 12-29"," 12-30","01-01")
That fixes the problem in this example. You can order all the dates by putting more spaces in front of earlier years. That will get messy.

Colleagues,

date<-c("12-29","12-30","01-01")
PT <- c(.106,.130,.121)
data <- data.frame(date,PT)
ggplot(data, aes(x=date,y=PT,group=1))+
  geom_point(size=4)+
  geom_line()+
  geom_hline(yintercept =c(1,.60,0,.30,.25,.2))+
  scale_y_continuous(label=scales::label_percent(),breaks=c(1,0.6,0,.3,0.25,0.2))+
  annotate("text", x=2.5, y=.1, label="Very Good",size=5,fontface="bold")+
  annotate("text", x=2.5, y=.225, label="Good",size=5,fontface="bold")+
  annotate("text", x=2.5, y=.28, label="Marginal",size=5,fontface="bold") +
  annotate("text", x=2.5, y=.45, label="Inadequate",size=6,fontface="bold")+
  annotate("text", x=2.5, y=.8, label="OOC",size=6,fontface="bold")+
  annotate("text", x=2.5, y=-.05, label="PT Not Done",size=5,fontface="bold")+
  theme_cowplot()

The plot has the wrong date order.
What is desired is 12-29, 12-30 and 01-01.

Some feedback would be appreciated.

All the best,
Thomas Subia
