Description

A class for model environments.

Objects from the Class

Objects can be created by calls of the form new("ModelEnv", ...).

na.fail returns FALSE when at least one missing value occurs in object@env. na.pass returns object unchanged and na.omit returns a copy of object with all missing values removed.

Examples

### a new object
me <- new("ModelEnv")

### define a bivariate response variable
me@set("response", data.frame(y = rnorm(10), x = runif(10)))
me

### check if a response is available
has(me, "response")

### the dimensions
dimension(me, "response")

### extract the data
me@get("response")

### NA handling
df <- data.frame(x = rnorm(10), y = rnorm(10))
df$x[1] <- NA
mf <- ModelEnvFormula(x ~ y, data = df, na.action = na.pass)
mf
na.omit(mf)
