Thanks jeff,
You are right about my expectation so if you have time please take a look
at this:
library(spdep)
test <- function () {
#read neighborhood list
neigh.gal <- read.gal("
http://sites.google.com/site/geosciej/Home/ter1RIorigM_T1.GAL?revision=1";)
#Making a weight matrix (listW)
w <- nb2listw(neigh.gal,style="B", zero.policy=TRUE)
sink("w.txt")
summary(w)
sink()
#Did the execution reached this point?
print("the function reached this point in the code")
}
and the result would be:
> test()
Error in print(data.frame(rbind(unlist(spweights.constants(object,
zero.policy = zero.policy))[c(1, :
error in evaluating the argument 'x' in selecting a method for function
'print': Error in spweights.constants(object, zero.policy = zero.policy) :
regions with no neighbours found
obviously the function does not go beyod sink().
the problem is at the print stage. the function does the job and this error
is expected but still it halts the execution of function running (and the
problem is not the sink() function, I tried).
I tried
try(test())
options(showErrorCalls=F)
options(show.error.messages=F)
for tryCatch() I could put the whole other part of the function in the
"finally" argument but it is not practical with many lines of code ahead.
I expect the code to continue executing regardless of any error or warning.
appreciate it
Ebrahim
