Loading SQLite table in R with RSQLite

问题:

I had this function I used to load a SQLite table

sqLiteConnect <- function(database, table) {
  library(DBI)
  library(RSQLite)
  con <- dbConnect("SQLite", dbname = database)
  query <- dbSendQuery(con, paste("SELECT * FROM ", table, ";", sep="")) 
  result <- fetch(query, n = -1, encoding="utf-8")
  dbClearResult(query)
  dbDisconnect(con)
  return(result)
}

But now it seams it generates an error

album <- sqLiteConnect("~/Downloads/ChinookDatabase1.3_Sqlite/Chinook_Sqlite.sqlite","Album")

Error in (function (classes, fdef, mtable)  : 
  unable to find an inherited method for function ‘dbConnect’ for signature ‘"character"’
Called from: stop(gettextf("unable to find an inherited method for function %s for signature %s", 
    sQuote(fdef@generic), sQuote(cnames)), domain = NA)

(I downloaded the db from here)

Is it a bug or a problem with my function?
