write.dbf error: invalid subscript type 'list'
Dear all, I am basically a GIS user and am new to R. I am trying to write a data frame to a dbf file. *n.simulations <- 999 binomial <- kulldorff(geo, cases, population, NULL, pop.upper.bound, n.simulations, alpha.level, plot) cluster <- binomial$most.likely.cluster$location.IDs.included df <- data.frame(ID=seq(1,n.simulations,by=1), simloglkhd=binomial$simulated.log.lkhd) write.dbf(df,"H:\\CIV\\CIVProject\\DATA\\plotdata.dbf&quo...

New package: DCluster
...thods to test Poisson extra-variation (Chi-square test and Potthoff-Whittinghill's test), Spatial Autocorrelation (Moran's I and Geary's c), general clustering (Whittermore's statistic and Tango's statistic), scan methods (Openshaw's GAM, Besag & Newell's methods and Kulldorff & Nagarwalla's statistic) and a focused test (Stone's Test). Bootstrap is used to estimate significance and a number of models are proposed to simulate data: permutations and Poisson, Multinomial or Neg. Binomial distributions. I hope the package will be useful to epidemiologists and...

A full description can be found here: http://www.ci.tuwien.ac.at/Conferences/DSC-2003/Proceedings/GomezRubioEtAl.pdf The purpose of this pre-release is to get feedback from the users.
