double caption in finalize about cmapplot

[nmpeterson]

As long as it remains backwards-compatible (i.e. a single string can still be supplied to the parameter, not wrapped in a c()) I have no problem with this. I guess it would just be a matter of checking whether the supplied value is a vector and, if so, returning cat(the_vector, sep = "<br><br>")?

yeah, I'm not even sure you'd need to check:

> caption <- c("This is a note.", "This is a source.")
> paste(caption, collapse = "<br><br>")
[1] "This is a note.<br><br>This is a source."

> caption <- "This is a note."
> paste(caption, collapse = "<br><br>")
[1] "This is a note."
