+## Are we being too verbose?
+
+One final note on `options()`.  4 of the core `{xportr}` functions have the ability to set messaging as `"none", "message", "warn", "stop"`. Setting each of these in all your calls can be a bit repetitive.  You can use `options()` to set these at a higher level and avoid this repitition.
+
+```{r, eval = FALSE}
+# Default
+options(
+    xportr.format_verbose = "none",
+    xportr.label_verbose = "none",
+    xportr.length_verbose = "none",
+    xportr.type_verbose = "none",
+)
+
+# Will send Warning Message to Console
+options(
+    xportr.format_verbose = "warn",
+    xportr.label_verbose = "warn",
+    xportr.length_verbose = "warn",
+    xportr.type_verbose = "warn",
+)
+```

 ## Going meta
 
 Each of the core `{xportr}` functions requires several inputs: A valid dataframe, a metadata object and a domain name, along with optional messaging. For example, here is a simple call using all of the functions. As you can see, a lot of information is repeated in each call.

 In order to be compliant with transport v5 specifications  an `xpt` file can only have two data types: character and numeric/dbl.  Currently the `ADSL` data set has chr, dbl, time, factor and date.

 Please observe that our `ADSL` dataset is missing many variable labels.  Sometimes these labels can be lost while using R's function.  However, a CDISC compliant data set needs to have each variable with a label.
