Basic vector methods for mdate objects

These methods let mdate vectors behave like ordinary character vectors for subsetting, replacement, concatenation, and repetition, while ensuring the result remains a validated mdate object.

Usage

# S3 method for class 'mdate'
x[..., drop = TRUE]

# S3 method for class 'mdate'
x[i, ...] <- value

# S3 method for class 'mdate'
x[[...]]

# S3 method for class 'mdate'
x[[i, ...]] <- value

# S3 method for class 'mdate'
c(...)

# S3 method for class 'mdate'
rep(x, ...)

Arguments

x

An mdate object.

drop

Included for consistency with the default [ method; has no effect since mdate objects are always vectors.

i, ...

Index or indices, as for the default methods; for c(), one or more objects to concatenate (coerced to mdate first).

value

A replacement value, coerced to mdate and validated before assignment.

Value

An mdate object, except for c(), which returns the (unclassed) result when called on a single object.

Examples

d <- as_messydate(c("2012-01-01", "2012-02-01", "2012-03-01"))
d[2]
#>  'mdate' chr "2012-02-01"
d[2] <- "2012-02-02"
c(d, as_messydate("2012-04-01"))
#>  'mdate' chr [1:4] "2012-01-01" "2012-02-02" "2012-03-01" "2012-04-01"
rep(d, 2)
#>  'mdate' chr [1:6] "2012-01-01" "2012-02-02" "2012-03-01" "2012-01-01" ...
