[R-sig-Geo] RE: [R] adjacency matrix

[Yang Aijun]

Dear R experts:

     The purpose of this e-mail is that I want to ask a question about "How
to get adjacency matrix from WINBUGS with ARCVIEW(.shp) files".As I can not
generate the "theme2.txt"  by convert.r .when I run the R project,it show
the problem as follows:
> source("convert.s")
> convert("theme2")
Read 289 records
Error in if (letter <= "9" & letter >= "0") { : 
        missing value where TRUE/FALSE needed

Would you please give me a help.Thank you!

Best regards

Aijun Yang
