WebThe default-value for this is na.omit, but with options(na.action = 'na.exclude') the default behavior of R can be changed. If it is not necessary to change the default behavior, but for a specific situation another na.action is needed, the na.action parameter needs to be included in the function call, e.g.:
Webna.exclude differs from na.omit only in the class of the "na.action" attribute of the result, which is "exclude". This gives different behaviour in functions making use of naresid and … Webna.action is a generic function, and na.action.default its default method. The latter extracts the "na.action" component of a list if present, otherwise the "na.action" attribute. When model.frame is called, it records any information on NA handling in a "na.action" attribute. Most model-fitting functions return this as a component of their result.
