[R] restructure my data

[arun]

Hi,
You could try:
df2<- do.call(cbind,split(df[,-1],df[,1]))

 res<-sapply(seq_len(ncol(df2)),function(i) {x<-df2[,i];x[duplicated(x)]<-NA;x})
dimnames(res)<- dimnames(df2)
res
#            0         1         2
#[1,] 1585.274 6462.3288  816.7808
#[2,] 2481.678  344.1781 6031.3356
#[3,] 8871.575        NA 4913.5274
#[4,] 1013.527        NA        NA
#[5,] 1517.250        NA        NA

Subject: [R] restructure my data

My data is in this form: var has 3 conditions (0,1,2)

> df
   var      cauc
1    1 6462.3288
2    0 1585.2740
3    0 2481.6781
4    1  344.1781
5    0 8871.5753
6    2  816.7808
7    2 6031.3356
8    0 1013.5274
9    2 4913.5274
10   0 1517.2500

For the three conditions (0,1,2) I want the cauc-values to be listed like
this

0                         1               2
1585,2740       6462,3288     816.7808
2481.6781      344.1781       6031.3356
...

Thanks Wim
