R不会用SQL块连接到html或pdf。eval中的错误（x，envir=envir）：对象'；连接'；找不到 connection

我已经修复了它，我把它放在了我的r设置中，现在只需执行{sql}来启动sql块

connection <- dbConnect(RSQLite::SQLite(), "AmericasCup.sqlite")
dbWriteTable(connection, "results", results, overwrite=TRUE)

```{sql connection=connection, output.var = "outQ6"}
SELECT Code, 
       SUM(Result = 'Win' ) AS Wins,
       SUM(Result = 'Loss') AS Losses
FROM results
GROUP BY Code

库（RSQLite）
图书馆（DBI）
连接
library(RSQLite)
library(DBI)
connection <- dbConnect(RSQLite::SQLite(), "AmericasCup.sqlite")
knitr::opts_chunk$set(connection = "connection")
