R help - Nov 2012 - generating sets of parameters, when some parameters are vectors

Hello,

I'm trying to generate N lists of randomly selected parameter values. Some
of the parameters are vectors while other are single values. I've tried to
use the approach below but it doesn't work for parameter x, which should be
a vector. Thanks in advance!

	  #Define names of parameters in the list,
parms<- list(
  x=c(0,0),
  y=0)

#Create N sets of randomly selected parameter values
N<- 10
set<-rep(list(parms),N)
for (i in 1:N) {
  set[[i]]["x"]=c(runif(1,1,2), runif(1,2,3))   ###Problem here
  set[[i]]["y"]=runif(1,5,10)
  }
