That's not the problem here. The variables are read as factors. You can
use the stringAsFactors argument of read.csv to turn this off:

that creates or appends to a zip file, allowing one to provide
alternative names.
I'll add support for writing content from memory (i.e. AsIs

Hi,
I would like to be able to repeat a string within a command. I think there
is an easy way but I can not figure out how.
Here is an example.
x-1:15
I would like to turn this into the following matrix:
xm-cbind(x,x,x,x,x)
But I would like to do so by having a command that repeats x within
Something like this:
do.call( cbind, rep(list(1:10), 5) )
[,1] [,2] [,3] [,4] [,5]
[1,]11111
[2,]22222
[3,]33333
[4,]44444
[5,]55555
[6,]66666
[7,]777
try this:
x - 1:5
x.list - lapply(1:15, function(a) x)
do.call(cbind, x.list)
[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] [,11] [,12]
[,13] [,14] [,15]
[1,]111111111 1 1 1
1 1 1
[2,]22222222

1) I am wondering is there a way to generate random numbers in R for
Bivariate Uniform distribution?
2) Does R have built-in function for generating random numbers for any
given bivariate distribution.
Any help would be greatly appreciated !!
