Dear Sir.. I am a graduate student in Pennstate. I have some problem in using R. At first, I used image function under R.(I loaded the packages GeoR, geoRglm, and coda) When I performed the following command "image(try4,loc=blue.grid,values.to.plot="median",col=gray(seq(1,0.1,l=9)),breaks=seq(9,89,l=10),xlab="X",ylab="Y")" I got some error message "Error in inout(pts = locations, ploy = borders) : subscript out of bounds " But I had no idea about this error. Would you give me some information or which part should I check again? Have a nice day. Sincerely Daeyoung Kim
