Hi .. i am a beginner in R I have data in the format of date 04/27/11 04/27/11 04/30/11 04/30/11 05/03/11 05/03/11 05/04/11....
So they are not yet dates, but rather character vectors. R dates don't look like that unless you make special efforts to mess them up.
Now i want to plot the data something like this on x-axis...
------------------
27 28 29 30 1 2 3 4
April May
I also wanted to know how to place a "*" when a date is missing from
the
data..
If you convert to dates, then the axis function should be able to properly label a plot. Read: ?DateTimeClasses
my other question is plotting the error bars.. since you can see that i have dates repeating. how to plot the error bars for count number of dates detected...
Need a better description of the data. So far you have only said you have dates. You should probably... no, make that definitely... read the Posting Guide.
I would appreciate if someone could answer as soon as possible...
Answers given to the extent possible given the limitations of the question.
thank you in advance..
