Dear All,
I have data frame:
set.seed(123.456)
df <-data.frame(ID=c(1,1,2,2,2,3,3,3,3,4,4,5,5),
read=c(1,1,0,1,1,1,0,0,0,1,0,0,0),
int=c(1,1,0,0,0,1,1,0,0,1,1,1,1),
z=rnorm(13,1,5),
y=rnorm(13,1,5))
what I would like to achieve (as best as I see it now) is to create multiple
lists (and lists within lists using the data in df) that would be based on the
groups in the ID column ("top level of list") and "join together" each line
item within the group followed by the next line item ("bottom level list"), so
would look like this for
[[ID=1]]
[[1]][[1]]
ID read int z y
1 1 1 5.188935 5.107905
1 1 1 1.766866 4.443201
[[ID=2]]
[[2]][[1]] ID read int z y
2 0 0 -4.690685 3.7695883
2 1 0 7.269075 0.6904414[[ID=2]]
[[2]][[2]] ID read int z y
2 1 0 7.269075 0.6904414
2 1 0 3.132321 -0.5298133[[ID=3]]
[[3]][[1]] ID read int z y
3 1 1 -0.4753574 -0.902355
3 0 1 5.4756283 -2.473535
[[ID=3]]
[[3]][[2]]
3 0 1 5.475628 -2.47353489
3 0 0 5.390667 -0.03958639
hoping example clear enough... all our help is appreciated,
thanks,
Andras
