I wrote a little utility function for exactly this reason, which I use with
long titles. You may want to add calls to par to adjust the upper margin if
you are using raw graphical functionality (plot et al) - but lattice adjusts
the upper margin automatically so you wouldn't need to add anything else.
PrettyString <- function(theString, maxLength, collapse = "\n")
{
words <- unlist(strsplit(theString, " "))
wordLengths <- unlist(lapply(strsplit(words, ""), length))
if(max(wordLengths) > maxLength)
stop("maxChar must be increased due to string length")
count = wordLengths[1]
results = vector()
currentLine = words[1]
for(i in 2:length(words))
{
if((count + wordLengths[i] + 1) > maxLength)
{
results = c(results, currentLine)
currentLine = words[i]
count = wordLengths[i]
}
else
{
currentLine = paste(currentLine, words[i])
count = count + wordLengths[i] + 1
}
}
if(length(currentLine))
results <- c(results, currentLine)
paste(results, collapse = collapse)
}
Knowing the R list, someone can probably reduce this function to 2 lines of
code.

Try This:
plot(A,main=paste("This is my really long title
and","\n","it's so long that
I can see
just about half of it.", sep = " "))

Try inserting \n into the title where you would like it to start on a new line, e.g.: plot(A,main="This is my really long title\nand it's so long\nthat I can see just about half of it.") You may need to give yourself more room in the margin for multi-line titles (see ?par and the mar entry) and using the title function (rather than in the plot) will let you specify the position of the title (line argument).

Shouldn't be that hard.You can insert newline characters ('\n') in the title: plot(A, main = "This is my really long title\nand it's so long that I can see\njust about half of it.") The likelihood is that you will need to alter the vertical position of the title to accommodate the line wrapping. To do that, you can either use mtext() in lieu of the 'main' argument, or consider adjusting par("mgp"), the first value of which is the position of the plot title. See ?mtext and ?par. You might also want to look at ?strwrap for a more general way of wrapping long lines of text. HTH, Marc Schwartz
try this:
plot(0, main=paste(strwrap("This is my really long title and it's so
long that I can see just about half of it.", width=50),
collapse="\n"))

Something like this will probably be close enough:
main="This is my really long title and it's so long that I can
see\njust about half of it."
