Utility functions

Usage

## S3 method for class 'sfc_sequence'
x[i]

## S3 replacement method for class 'sfc_sequence'
x[i] <- value

## S3 method for class 'sfc_sequence'
length(x)

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

Arguments

x	An 'sfc_sequence' object.
i	Numeric index.
value	An 'sfc_sequence' object.
...	A list of 'sfc_sequence' objects or other arguments.

Details

For efficiency, 'c.sfc_sequence()' does not check whether the input 'sfc_sequence' objects are compatible.

Value

'length.sfc_sequence()' returns an integer scalar.

'c.sfc_sequence()' returns an 'sfc_sequence' object.

Examples

p = sfc_sequence("ABCDEFGH")
p
p[1:4]
p[1:4] = p[8:5]
p
length(p)
c(p, p)
