Constant interpolation modelling option for spherical coordinates (AverageR and TimeR)

[arunge]

@mgross Please let me know, when you start working on the following planed feature:

For models AverageR and TimeR: Constant interpolation modelling option for spherical coordinates

Possibly we can split the task, let me know which inputs you require and what kind of output we need to display. I will create the user inputs and the output and you can provide the code for the calculation. For this, please:

• name required inputs and the type of input
• describe the expected output
• provide the code for the calculation

Your provided code should contain:

1. a file with example input data (.csv or .xlsx) or an R script containing a dataframe/list with example input data
2. an R script containing a function for the calculation. Please add the documentation for the parameters of the function.

• please name all required functions and libraries that are used for the calculation

3. a file containing the expected output (.csv or xlsx file or an R script containing the expected dataframe/list)

Note on error handling: In order to throw errors please include conditions inside your code, e.g.

if (<some invalid condition>) stop("<Some error message>")

if (<some condition where the user should receive a warning>) warning("<Some warning message>")

stop(...) and warning(...) statements I will catch from outside the function and forward them to the user with the shinyTools::shinyTryCatch() function.
Errors/warnings that come from other functions that are called inside of your function will be caught automatically.

Please, let me know if you have any questions.

We need to use this package with the following settings:

s(latitude,longitude,bs="ds",m=-2)

mgcv_1.8-34.tar.gz

[arunge]

@mgross Could you please give some more details?

I checked following lines:

DSSM/R/03-modelResults2D.R

Lines 74 to 77 in 65ed7a0

	radioButtons(inputId = ns("SplineType"),
	label = "Smooth type",
	choices = c("planar" = "1", "spherical" = "2"),
	selected = "1"),

DSSM/R/03-modelResults2D.R

Lines 80 to 83 in 65ed7a0

	radioButtons(inputId = ns("Penalty"),
	label = "Extrapolation behaviour",
	choices = c("constant" = "1", "linear" = "2"),
	selected = "2"),

DSSM/R/01-estimateMap.R

Lines 1041 to 1049 in 65ed7a0

	if (splineType == 2){
	bs = "sos"
	} else {
	bs = "ds"
	}
	penalty <- penalty %>% updatePenalty(bs = bs)
	s <- smoothCon(s(Latitude, Longitude, k = nknots, bs = bs, m = penalty),
	data = data, knots = NULL)[[1]]

When having "sperical" Smooth type, one can select "constant" Extrapolation behaviour:

So, we need a new input for "Interpolation behaviour" and an option for "constant"?? What else options would we need?
