[R] ggplot aestetics: beginner question - I am lost in endless possibilites

[John Kane]

I cannot see how you get that code to run. It certainly does not on my machine and some of the manipulations don't make any sense as far as I can see.
I changed variable and data.frame names so I would not have to type so much and read in the data with the "stringsAsFactors = FALSE" option.
I then parsed the dates (called 'known' in my data.frame) using the package "lubridate"
dat1$mydate <- dmy(dat1$mydate)

My resulting data.frame called dat1 is presented in dput() format below.
Do I understand you correctly in that you want the NA values plotted as "white" and the outline on the tiles in black?
In any case as my first steps here is a revised program to just get the tileswith no effort to get the outline or change the colours of the fill.

#This is my string:

              recordedTime=c("03.01.2011","04.01.2011","05.01.2011",
"04.01.2011","05.01.2011","06.01.2011"),
                knownstate =c("breeding","moulting","moulting",
                              "breeding","breeding",NA))
exdatframe

exdatframeT <- as.POSIXct 
(strptime(as.character(exdatframe$recordedTime),"%d.%m.%Y"))
exdatframeT
exdatframe2 <- cbind(exdatframe, exdatframeT)
exdatframe2$recordedTime <-NULL
exdatframe2
str(datframe)

library(ggplot2)
ggplot(exdatframe2)+geom_tile(aes(x=exdatframeT,y=Name,fill=knownstate), 
height=0.5)

# Now all I want is:
# 1) a black outline around the bars. Adding colour="black" like I have 
found elsewere on the internet doesn't work
# 2) change the colours: E.g. I want white for NAs. I can't find a 
command to describe my wishes.
