about CL3 and CL4 formats

about CL3 and CL4 formats Note: despite the internal labeling, the sample files vt_500k2_hex_pop80.cl4 and RLInt.out.0016 are in CL4 (not CL3) format. The current version of RLInt expects files in CL4 format.

CL3 (CLOSE3) files contain lines with three fields, of the form

43502.6	9036.70		59097.5  targ area, pop, orig area

CL4 (CLOSE4) files contain lines with six fields, of the form

43502.6	9036.70	59097.5  0  0  0 targ, pop, orig, cases
The last three fields represent, respectively, (a) the number of true cases in this polygon (b) the number of true cases with random locations within their respective tracts (c) the number of random cases generated under the null hypothesis. The examples given here include no cases of type (a), (b) or (c).
