Hello,
I have an x, y data set of circa 966 points, and counting, where I am trying to
plot one integer y-axis number per a corresponding x-axis date, in R. The
command plot(initialPlot$Dates, initialPlot$AxisData), where $Dates is
2007-07-24:2010-03-15, and $AxisData is the corresponding y coordinates, results
in an accurate x-axis, but unusable plot, as lines and points are not generated,
only dashes for the plot. I wrote a simple C++ program, and stripped out the
dates to Year, month, and day data sets (eg. 2007, 08, 01), and used these sets
as arguments to ISODate, but this did not work, as the month data set does not
appear to be the correct argument for ISOdate used in this manner. I have
looked, but not found an example that shows how this is done in R. An example
point would look like (2007-24-07, 109), where the data would be input by
read.table(), and appear in R as:
Date AxisData
2007-07-24 109
. .
. .
. .
2010-03-15 102
A usable plot would have an accurate x-axis, displaying the correct date
interval, and a point-line trace representing the y-axis coordinates.
plot($AxisData) achieves this successfully, as the x-axis defaults to the number
of inputs). Any help you all may provide will be greatly appreciated. If more
information would be helpful, please let me know.
Cheers,
John
