Subject: Qustion about Creating a sequence of vector
Hello R User,
I have a data set where subject( Id) are frequently measured. For
example, the size of the data set is 75 by 2 and has following
frequency distribution.
id freq
1 30
2 20
3 25
I want to create a variable (say seq) containing sequential count for
each id. I mean variable seq should be as ( 1,2,..,30, 1,2,...,20,
1,2,...,25)
I use following code but did not work. Any suggestion is much appreciated..
sim<-rep(NA, 90)
for (i in 1:3){
d[i]<-seq(1,a[i,2],by=1)
sim[i]<-as.vector(c(d[i])
}
Thank you,
Bibek
