Handle Missing Values in Objects
Description
These generic functions are useful for dealing with NAs
in e.g., data frames.
na.fail returns the object if it does not contain any
missing values, and signals an error otherwise.
na.omit returns the object with incomplete cases removed.
Usage
na.fail(object)
na.omit(object)
Arguments
object |
an R object, typically a data frame |
Details
At present these will handle vectors, matrices and data frames comprising vectors and matrices (only).
If na.omit removes cases, the row numbers of the cases form the
"na.action" attribute of the result, of class "omit".
See Also
na.action, options(na.action=..) for setting “NA
actions”, and lm and glm for functions
using these.
Examples
DF <- data.frame(x = c(1, 2, 3), y = c(0, 10, NA))
na.omit(DF)
m <- as.matrix(DF)
na.omit(m)
