SQLiteテーブルをロードするために使用したこの関数がありました
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)
}
しかし、今では継ぎ目でエラーが発生します
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)
(ここからdbをダウンロードしました)
それはバグですか、それとも私の機能の問題ですか?
