In particular, Duncan's comment applies in situations where the
replacement is in a loop, obviously the case one worries about.
What happens in the stupid little function:
> foo <- function(x) { for(i in seq_along(x)) x[i] <- x[i] +1; x}
for the case
> y <- 1:1e6
> y1 <- foo(y)

Sounds like a good idea. The RCurl package can also do the base64
encoding (depends on libcurl), e.g.
library(RCurl)
img <- function() {
tf <- tempfile()
tf.out <- tempfile()
png(tf, width = 500, height = 500)
plot(1:100, rnorm(100), pch = 21, bg = "red", cex = 2)
dev.off()
