Hi,

i'm using the 'col.gal.nb' object for the definition of all neighbors. my
information is loaded from a archives into may pc
Though someone might accidentally know what col.gal.nb is and where it 
comes from, having told us here would have been much nearer to 
'reproducible'.
*library(spdep)*
*
*
*city<- readOGR(dsn="C:/cities", layer="city1")*
*coords<- coordinates(city)*
*
*
*plot(col.gal.nb, coords, add=TRUE)*
*Error: length(nb) == nrow(coords) is not TRUE*
If you refer to the documentation of the plot method you are using here, 
I suspect you find out that 'nb' refers to the first argument and 
'coords' to the second. The error message tells you they need to fulfil 
the condition given in the message ('length(nb) == nrow(coords)' is 
actually an R expression!).

HTH,
Tom
but when i try to draw it, an error appears. i don't know what could be the
error...
