You can use paste to construct that actual query.

dat <- matrix(1:4, 2, 2)
query <- paste("INSERT INTO names VALUES(",data[1,1], ",", data[1,2], ")")
query
#[1] "INSERT INTO names VALUES( 1 , 3 )"
dbGetQuery(con, query)

# If there are a lot of columns this could be tedious...
# So we could also use paste to add all the values at once.
query <- paste("INSERT INTO names VALUES(", paste(data[1,], collapse = ", "), ")")
query
#[1] "INSERT INTO names VALUES( 1, 3 )"
