Hi,
tryCatch seems to be evaluating the all expressions wrapped in it before passing
control to the error handling function. For example, the code below will try to
evaluate "results" even though the call to odbcConnect fails. I was
hoping that the mechanism would work in the same way as a C++ try catch
structure and pass control to the catch... as soon as an exception is generated.
Am I expecting too much or is there a way to tryCatch... multiple statements in
R?
tryCatch(
{
conn<-odbcConnect(...
results<-sqlQuery(...
}
,
error=function(err)myErrorHandler(...
)
.
