Methods for "[" and "[<-", i.e., extraction or
subsetting of brobs and glubs.
Usage
# S4 method for class 'brob'
x[i, j, ..., drop = TRUE]
# S4 method for class 'glub'
x[i, j, ..., drop = TRUE]
# S4 method for class 'brobmat'
x[i, j, ..., drop = TRUE]
# S4 method for class 'brob'
x[i, j, ...] <- value
# S4 method for class 'glub'
x[i, j, ...] <- value
# S4 method for class 'brobmat'
x[i, j, ...] <- value
Arguments
- x
Object of class brob or glub
- i, j, ...
elements to extract or replace
- value
replacement value
- drop
Boolean, indicating whether to drop the result
Value
Always returns an object of the same class as x.

Note
If x is a numeric vector and y a brob, one might expect
typing x[1] <- y to result in x being a brob. This is
impossible, according to John Chambers.
Examples
a <- as.brob(10)^c(-100,0,100,1000,1e32)
a[4]
#> [1] +exp(2302.6)
a[4] <- 1e100
a
#> [1] +exp(-230.26) +exp(0) +exp(230.26) +exp(230.26)
#> [5] +exp(2.3026e+32)
