[R] Graph binned data

[Jeffrey Joh]

I have a table that looks like this:

structure(list(speed = c(3,9,14,8,7,6), result = c(0.697, 0.011, 0.015, 0.012, 0.018, 0.019), house = c(1, 
1, 1, 1, 1, 1), date = c(719, 1027, 1027, 1027, 1030, 1030), 
    id = c("1000", "10000", 
    "10001", "10002", "10003", "10004")), .Names = c("speed", 
"result", "house", "date", "id"), class = "data.frame", row.names = c("1000", 
"10000", "10001", "10002", "10003", "10004"))

I would like to bin the data by speed, 0-4, 5-9, 10-14, 15-20, etc.  Then I would like to make a graph of speed vs result.  The graph should show the average result of each bin, and error bars to represent the standard deviation of the result in each bin.  What kind of code can I use to make this?
