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(...
)
.
