Dear R users,
I am having problems making a boxplot across time. I wish to plot the
"Values" (y-axis) against "Date" (x-axis) but would like the Date to be
sequential from 2007-11-15 until 2008-01-31 (therefore there will be lots of
NA's e.g. from 2007-11-16 to 2007-11-26 nothing will show in the plot).
Please see sample table below. Also would like to show in the x-axis only
the labels for the first day of the month.
I tried the following but it didn't work as I hoped as the x-axis is not in
a sequence, is only the Dates in the table:
- boxplot(Values~as.Date(Dates,format="%d/%m/%Y"),
at=unique(as.Date(Dates,format="%d/%m/%Y")))
mytable
Date Values
2007-11-15 4.882687861
2007-11-15 3.987085185
2007-11-27 4.012696575
2007-11-28 5.294707110
2007-11-28 4.033201550
2007-11-28 5.364524511
2007-11-28 5.002159389
2007-11-29 4.221255553
2008-01-11 4.154506592
2008-01-11 4.587936354
2008-01-16 4.188505351
2008-01-16 4.491573677
2008-01-28 5.054001005
2008-01-28 4.204093421
2008-01-29 4.597323620
2008-01-29 5.082882698
If someone could help me I would be very thankfull.
Best regards
