below i think semi does what you want but it's never going to repeat a
value because it's sampling without replacement ? in that sense,
it's not as general as what you asked for. if you need the repeating
thing, then i'm not sure how to do that. hopefully someone else does.
lapply(1:30, function(.index) {
sample(1:.index,replace=FALSE,size=.index)
})

hi
thanks for the reply
actually am supposed to generate random numbers in oncreasing size.
so when i say 1,2 i should get something like 12222 or 221 or 1112
...i
should get both the values 1 and 2 in a random order but it should
stop when
both the values occur atleast once in the sequence.so after 1,2 it
should be
1,2,3 and the sequence generated should have 1,2,3 atleast once.then
it
should generate a random sequence of numbers 1,2,3,4 ...it should go
on till
it generates 1,2....30.hope am clear now.

i have to generate random numbers from length 2 to 30 and length two
should have the numbers 1,2 and length 3 should have the numbers
1,2,3 so
on and so forth till size 30.i should get an sequence like 2222221 or
1111112 till both the values appear and for 3 it should be 1222223 or
3331112.i should get similar output for all sizes which means i
should get
30 sequences.but am getting only one sequence .please help.
this is my code
y=0;
for (i in 1:3)
{
while(y!=i)
{
y=sample(1:3,replace=TRUE);
}
}
