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
