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)
