how to generate uniformly distributed random integers
I'm a beginner of R. I can use runif() to generate uniformly distributed numbers, but I don't know which function can generate uniformly distributed random integers, or what kind of method do? Thanks! -- View this message in context: http://www.nabble.com/how-to-generate-uniformly-distributed-random-integers-tf4960778.html#a14208376 Sent from the R help mailing list archive at

ploting dots with quentiles
http://r.789695.n4.nabble.com/file/n2260087/%E6%8D%95%E8%8E%B7.png I am going to plot my data set like this, with means and 25% & 75% quentiles. I've tried "boxplot", but the output is not what I want. Should I use other functions?
