In OHDSI/LocalControl: Nonparametric Methods for Generating High Quality Comparative Effectiveness Evidence

Plot the LTD distribution as a function of the number of clusters.

Description

This function creates a plot displaying the distribution of Local Treatment Differences (LTDs) as a function of the number of clusters created for all UPSnnltd objects in the provided environment. The hinges and whiskers are generated using boxplot.stats.

Usage

UPSLTDdist(envir, legloc = "bottomleft", ...)

Arguments

envir	A LocalControlClassic environment containing UPSnnltd objects.
legloc	Where to place the legend in the returned plot. Defaults to "bottomleft".
...	Arguments passed on to graphics::plot.default type 1-character string giving the type of plot desired. The following values are possible, for details, see plot: "p" for points, "l" for lines, "b" for both points and lines, "c" for empty points joined by lines, "o" for overplotted points and lines, "s" and "S" for stair steps and "h" for histogram-like vertical lines. Finally, "n" does not produce any points or lines. xlim the x limits (x1, x2) of the plot. Note that x1 > x2 is allowed and leads to a ‘reversed axis’. The default value, NULL, indicates that the range of the finite values to be plotted should be used. ylim the y limits of the plot. log a character string which contains "x" if the x axis is to be logarithmic, "y" if the y axis is to be logarithmic and "xy" or "yx" if both axes are to be logarithmic. main a main title for the plot, see also title. sub a subtitle for the plot. xlab a label for the x axis, defaults to a description of x. ylab a label for the y axis, defaults to a description of y. ann a logical value indicating whether the default annotation (title and x and y axis labels) should appear on the plot. axes a logical value indicating whether both axes should be drawn on the plot. Use graphical parameter "xaxt" or "yaxt" to suppress just one of the axes. frame.plot a logical indicating whether a box should be drawn around the plot. panel.first an ‘expression’ to be evaluated after the plot axes are set up but before any plotting takes place. This can be useful for drawing background grids or scatterplot smooths. Note that this works by lazy evaluation: passing this argument from other plot methods may well not work since it may be evaluated too early. panel.last an expression to be evaluated after plotting has taken place but before the axes, title and box are added. See the comments about panel.first. asp the y/x aspect ratio, see plot.window. xgap.axis,ygap.axis the x/y axis gap factors, passed as gap.axis to the two axis() calls (when axes is true, as per default).

Value

Returns the LTD distribution plot.

Adds the "ltdds" object to envir.

Examples

 data(lindner)
 cvars <- c("stent","height","female","diabetic","acutemi",
            "ejecfrac","ves1proc")
 numClusters <- c(1, 2, 10, 15, 20, 25, 30, 35, 40, 45, 50)
 results <- LocalControlClassic(data = lindner,
                                clusterVars = cvars,
                                treatmentColName = "abcix",
                                outcomeColName = "cardbill",
                                clusterCounts = numClusters)
 UPSLTDdist(results,ylim=c(-15000,15000))
