sjedrp.d10 | R Documentation |
Example data sets for checking the DRP code. These data sets have been run on Rodieck's program for comparison.
data(sjedrp.d10)
Two columns of data; first column is x coordinate; second column is y coordinate.
Stephen Eglen
These data sets are artificial; they were created with the dmin rule.
Rodieck RW (1991). The density recovery profile: A method for the analysis of points in the plane applicable to retinal studies. Visual Neuroscience 6: 95-111.
autodrp for the main code, and rodieckach for the data to generate the DRP from Rodieck (1992). See other data sets such as sjedrp.d20, sjedrp.d25 and sjedrp.d30.

bb <- c(0, 700, 0, 700)
res <- autodrp(sjedrp.d10$x, sjedrp.d10$y, nbins=20, r=10, a=bb)
