[R] match from a data.frame in dependence of an ID

[arun]

Hi,
Try:
#dat is the dataset:

library(plyr)
dcast(dat,ID~Group,value.var="value",fill="")
#or

dcast(dat,ID~Group,value.var="value",fill=0)

Hello togehter,

i have a litte problem. I have an output data.frame which look like this
one:
    ID          
1  10        
2  11
3  12

Now I have another data.frame with more than one line for each ID:
    ID    Group    Value
1  10    1            10
2  10    2            20
3  10    3            30
4  10    4            40
5  10    5            50
6  11    3            60
7  11    4            70
8  12    4            80

How can i match these two data.frame for the following result:

    ID    1     2     3     4     5          
1  10    10   20    30   40   50
2  11                 60   70
3  12                       80
