Subject: Re: [R] Selecting First Incidence from Longitudinal Data
sorry, I tried this. But it gave me answer:
# ID COMPL SEX HEREDITY
#1 1 0 1 2
#4 2 0 0 1
#8 3 0 0 1
#13 4 0 1 2
I have a longitudinal competing risk data of the form:
IDCOMPL SEX HEREDITY
1 0 1 2
1 0 1 2
1 3 1 2
2 0 0 1
2 1 0 1
2 2 0 1
2 2 0 1
3 0 0 1
3 0 0 1
3 0

Hello,
You can use ?aggregate and ?head to do what you want. Try the following.
dat - read.table(text=
IDCOMPL SEX HEREDITY
10 1 2
10 1 2
13 1 2
20 0 1
21 0 1
22 0 1
22 0 1
30 0
Try this:
dat$sequence - as.vector(unlist(lapply( aggregate(dat$ID, by=list(x),
FUN=length)$x, FUN=function(x){seq(1, x
dat0 - dat[dat$sequence==1, ]

To account for COMP,
dat$sequence - as.vector(unlist(lapply( aggregate(dat$ID, by=list(dat$ID),
FUN=length)$x, FUN=function(x){seq(1, x
dat0 - dat[dat$sequence==1 dat$COMPL!= 0, ]
