[R] How to set up a function for "Central Limit Theorem"

Hello guys, I am stuck here: How do I make 1000 samples of n = 10 observations from an Exponential distribution and then compute the mean for all those 1000 samples? Basically I need to prove the Central Limit theorem, which states: http://www.nabble.com/file/p22664113/d175f06cbf200bd52a2c27a2

Re: [R] Using color and plotting characters in a scatterplot matrix [Newbie Help]

I figured out how to do the rest, the only thing I need to do now is to somehow change the numbers which are < 90 to a character string "low" . The values which are between 100 - 90 to convert to character string "medium". And the values larger than 100 to convert to character string "high". Then
