R 不会编织到 html 或 pdf 与 Z9778840A0100CB30C98Z2876A4 块。 eval 中的错误（x，envir = envir）：未找到 object '连接'

Question

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

Everything runs fine but when I try knit to html or pdf I get the following error: Line 79 is: SELECT Code,

Can anyone tell me what the problem is here, I have tried to research this but cant find anything similar, though I suspect it has something to do with my '''{sql connection=connection, output.var - "outQ6"} setup.

Thank you in advance.

Answer 1

I have fixed it, I put this in my r setup instead and now just do {sql} to start sql chunk.

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