Hi - My problem is frustratingly simple, but I’ve struggled with it long enough that I need to reach out for help.
I need to work with data from elevation measurements regularly spaced around a circle. The number of measurements varies from 8 to 30 (I attach a sample 16-spot file). I successfully import from a CSV file, flatten the data no problem, and I have a 1-dimensional matrix od length n.
S = Flatten[Import["desktop/Settlement Data.csv"]]
n = Length[S]
To work with the data, though, I need to represent its angular coordinate instead of its List position. The measurements are regularly spaced around the circle, so it’s simple enough to build a 1-D table of the angular coordinates that correspond with each measurement:
R = Drop[Table[i, {i, 0, 2 Pi, (2 Pi/n)}], -1]
The problem: How do I combine the two tables into {Measurement, Angle} pairs so I can PolarPlot{ S,R} instead of ListLinePlot~~? This is the best that I can do, but it doesn’t actually create the 2-d table I need for cosine curve fitting:~~
ListLinePlot[S, DataRange -> {0, 2 Pi}, Filling -> Axis, Ticks -> {{0, Pi/2, Pi, 3 Pi/2, 2 Pi}, Automatic}]
Any suggestions greatly appreciated.
