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)
