[R] match values in dependence of ID and Date

[Mat]

hello togehter,

i have a little problem, maybe you can help me.

I have a data.frame like this one:

ID    Name
1     Andy
2     John
3     Amy

and a data.frame like this:

ID   Date            Value
1    2013-10-01    10
1    2013-10-02    15
2    2013-10-01    7
2    2013-10-03    10
2    2013-10-04    15
3    2013-10-01    10

the result should be this one:

ID    Name   First   Second    Third
1     Andy    10     15
2     John     7      10           15
3     Amy     10

maybe you can help me, to do this?

Thank you.

Mat
