[R] Passing arguments to SQL Query in R

I am a newbie at R, with some experience in PERL.
I have a database table that contains the following data:
Name | Score
======= | =====
Sachin T | 25
Sachin T | 53
Sachin T | 57
Sachin T | 34
Rahul D | 38
Rahul D | 31
Rahul D | 53
Ricky P | 7
Ricky P | 45
Ricky P | 27
Ricky P | 17
Ricky P | 86
Ricky P | 48
Jacques K | 23
Jacques K | 86
Jacques K | 32
I want the summary data as below:
Name | Avg Score
Currently, I am trying to pass the name of the person as an argument in a
sql query by breaking the query into parts, and then concatenating the query
string. Of course, the scheme is not working.
I want a query as below:
SELECT NAME, SCORE FROM PLAYER_SCORE_TBL where NAME = ?
Then I can pass the parameters like we do in PERL.
If there is an alternative to the whole scheme, that would be wonderful. a
way that would just take the whole table, and provide pivot table like
Thanks in advance,
