Generate a sequence of vectors of different length

Hi everyone
After the following setup

sector=2 # Define Number of Sectors

sectors=LETTERS[seq( from = 1, to = sector )] # Name sectors

No_ent=round(3/runif(sector)) # Number of entities per sector

#Tot_No_ent=sum(No_ent)



Goal is to get a List like

(A1, A2, A3, B1, B2, B3, B4) where A is denoting an industrial sector and
then a numbered sequence of companies within the sector.



The step I am missing is how to generate a sequence of vectors (one for each
sector) with individual length being determined by No_ent.

The goal is to generate a set of entities from different sectors. One simple
way out of it would be to set the number of entities equal per sector and
have a matrix, but I am quite sure it should also be possible for having a
different number of entities in each sector.



Once this is done, I can bind them together as vector with
"as.vector(rbind(?))" (both as an (A,A,A,B,B,B,B) and (1,2,3,1,2,3,4) and
then concatenate)



Thanks, Christian





Trials included the following bits

A=for (i in 1:sector){

rep(i,No_ent[i])

}

paste(LETTERS[i], seq(from =1, to =No_ent[i]), sep = "")

but I don't get the correct object definition right.
