Very easy if you note that cex in plot can be a vector.

y-runif(100)

Dear all
How does one convert a non-symmetric list to a vector? See below:
x - list()
x[[1]] - letters[1:5]
x[[2]] - letters[6:10]
x[[3]] - letters[11:12]
x

Hello,
I am a R beginner and hoping to obtain some hints or suggestions about
using permutations to sort a data set I have.
Here is an example dataset:
Ind1 11 00 12 15 28
Ind2 21 33 22 67 52
Ind3 22 45 21 22 56
Ind4 11 25 74 77 42
Ind5 41 32 67 45 22

Hi,
For some reason I'm finding that my table caption is disappearing if I

To pick random elements to sample, you can just use the sample function
sample(1:5,3,replace=T/F) # pick true or false as needed for your data.
If you replicate this, you should have no problem.
replicate(100,function() return(sample(1:5,3,replace=T/F)))
This will be plenty fast, but if you

I am using the clustering functions in R in order to work with large
masses of binary time series data, however the clustering functions do not
seem able to fit this size of practical problem. Library 'hclust' is good

Sorry, that second line of code won't work: do it in 2.
