If you look below at the detritus of your posting you will see why we are
always reminding people to adjust their email programs to send PLAIN
TEXT... since this is a plain text mailing list and HTML formatted email
does not come through reliably. This and other ground rules are laid out
in the Posting Guide mentioned in the footer of every email on the mailing
list.
I also recommend looking into the reprex package... it can conveniently
check any code example to confirm that it is self-contained so it should
run on our computers and we can see your progress. The dput function is
also useful for giving us a snippet of data in our R environments (not
much to look at, but makes R quite happy). I am going to pass on trying to
decipher the mess below.
However, I think the key to answering your query is learning how to create
factor columns in your data set (hint: use the factor function, not the
as.factor function). The order of the labels in the factor is preserved in
the plot (assuming the structure of the plot is not too complicated), so
you can use scale_* functions such as scale_fill_manual to control the
corresponding graphical appearance.

Hi,
I am new to R and this is probably a very basic question but I can?t seem to
figure out a solution. I am creating a stacked ggplot with the following data
and code:
PercentageData.csv looks like this:
decision
treatment
percentage
labtreatment
defect
0
53.49
COMMON
defect
1
78.00
ASYMMETRIC
defect
2
96.67
PRIVATE
coop
0
46.51
COMMON
coop
1
22.00
ASYMMETRIC
coop
2
3.33
PRIVATE
%Load data:
charts.data <- read.csv("PercentageData.csv?)
%create stacked ggplot
p4 <- ggplot() + geom_bar(aes(y = percentage, x = treatment, fill = decision), data =
charts.data, stat="identity")
p4
%y-axis is percentage and x-axis is treatment, ordered 0, 1, 2
I?d like to have the treatment names be strings so that 0=?COMMON?, 1=?ASYMMETRIC?, 2=?PRIVATE?. How do I assign names to the treatment variable?
I?ve tried to just have a new variable, x=labtreatment, but then the order of
my data is graphed alphabetical (and not what I am looking for); Asymmetric on
the left, Common in the middle, then Private on the right. Is there an easy way
to reorder this?
Thanks for any help!
Best,
Mary
