read.csv.sql() to select from a large csv file

Dear list,

Dear list,
I am using read.csv.sql() from the sqldf package to read
individual-based data from a csv file that is too large for R.
My original file contains a column called ?ID? that
identifies the individual. I would like to read in data for only
one individual at a
time, for example "Bobby".
read.csv.sql("filename",sql = 'select * from file where ID = ?Bobby?') works fine, but
Name <- "Bobby"
read.csv.sql("filename",sql = 'select * from file
where ID = Name') gives me an error message
 ?Error in sqliteExecStatement(con, statement,
bind.data) :
RS-DBI driver: (error in statement: no such column: Name)?

I would like to use a variable in the select statement because I have many individuals in the original csv file, is this possible ? I have no experience with sql, perhaps someone can kindly point out how to do this correctly or offer an alternative solution ?
