Running the function hwx.test can create data for a frequency distribution plot of one of the four test statistics provided the parameter histobins is positive. These plotting data are contained within the “hwtest” object generated by hwx.test. When that object is printed, a plot is drawn by ggplot2. If the user wishes to capture the ggplot2 results, such as to use in making a composite figure, the “gg” object can be obtained by calling makeHistogram.
defaultHistobounds(ostats, statID, m)makeHistogram(x, curveColor = "blue", color1 = "gray40",
color2 = "lightcoral")
Observed statistics for the 4 test measures, LLR, Prob, U and Chisq.
Value 1-4 indicating which statistic to use for the plot.
vector of allele counts
output from hwx.test
color for the asymptotic distribution curve
The color for outcomes fitting the null distribution better than the observed
The color for outcomes deviating from the null at leasst as much as observed. Area of color2 is the P value.
defaultHistobounds returns a vector containing the left and right boundaries for the x axis. This function is not normally called by the user
makeHistobram A graphic object of class “gg” or “ggplot” from ggplot2.
