:Re: [R] creating table with sequences of numbers based on the
table
I think this'll be way simpler and also faster:
ans <- data.frame(pop = rep.int(tab$pop, tab$Freq), ind=sequence(tab$Freq))

Less coding with plyr:
tab <- read.table(text="pop Freq
1 1 30
2 2 25
3 3 30
4 4 30
5 5 30
6 6 30

Hi,
Try:
Either
tab <- read.table(text="pop Freq
1 1 30
2 2 25
3 3 30
4 4 30
5 5 30
6 6 30
7 7 30",sep="",header=TRUE)
indx <- rep(1:nrow(tab),tab$Freq)
tab1 <- transform(tab[indx,],ind=ave(seq_along(indx),indx,FUN=seq_along))[,-2]
#or
tab2
