我試圖從R到MonetDB(使用MonetDB.R)連接(dbConnect())時出現錯誤。有一個(related SO question),我也嘗試了那裏的sugestions((a)使用MonetDB.R測試版0.9.5或(a)使用常規MonetDB.R但用早期版本(0.2-7)替換DBI軟件包)沒有成功。R> Monetdb,dbConnect錯誤(包Monetdb.R)
這是代碼和錯誤:
library(MonetDB.R)
options("monetdb.sequential" = TRUE)
setwd("C:/Users/lucas_000/Desktop/Curso R/importa_RAIS")
batfile <-
monetdb.server.setup(
database.directory = paste(getwd() , "/MonetDB", sep="") ,
monetdb.program.path =
ifelse(.Platform$OS.type == "windows" , "C:/Program Files/MonetDB/MonetDB5" , "") ,
dbname = "RAIS" , dbport = 50003
)
batfile <- "C:/Users/lucas_000/Desktop/Curso R/importa_RAIS/MonetDB/RAIS.bat"
dbname <- "RAIS"
dbport <- 50003
pid <- as.numeric(monetdb.server.start(batfile))
# output indicates: MonetDB 5 server v11.17.21 "Jan2014-SP3"
db <- dbConnect(MonetDB.R() , "monetdb://localhost:5003/RAIS" , wait = TRUE)

嘗試的解決方案和相應的錯誤:
一)試圖安裝MonetDB.R_0.9.5.zip(測試版)
library(devtools)
remove.packages("MonetDB.R")
install_url("http://homepages.cwi.nl/~hannes/R/MonetDB.R_0.9.5.zip")
* installing *binary* package 'MonetDB.R' ...
cp: unknown option --)
Try `/usr/bin/cp --help' for more information.
Aviso: execução do comando 'cp -R . "C:/Users/lucas_000/Documents/R/win- library/3.1/MonetDB.R" || (tar cd - .| (cd "C:/Users/lucas_000/Documents/R/win-library/3.1/MonetDB.R" && tar -xf -))' teve status 1
ERROR: installing binary package failed
* removing 'C:/Users/lucas_000/Documents/R/win-library/3.1/MonetDB.R'
Error: Command failed (1)
B)保持MonetDB.R普通版(CRAN),但改變DBI到以前的版本(也sugested上SO):
remove.packages("DBI")
library(devtools)
install_url("cran.r-project.org/src/contrib/Archive/DBI/DBI_0.2-7.tar.gz")
library(DBI)
db <- dbConnect(MonetDB.R() , "monetdb://localhost:5003/RAIS" , wait = TRUE)
#給人同樣的錯誤如上, 斷言失敗! 程序:C:Program Files文件\ RStudio \ BIN \ 64 \ rsession.exe 文件:mapi.c,線路91 表達:IS_INTEGER(端口) #Then RStudio顯示錯誤: 「R會話中止」
測試版本是一個二進制包,你可以嘗試通過「從zip文件安裝包」路線安裝嗎? – 2014-10-06 06:41:04
嗨,'MonetDBLite'(在CRAN上)現在取代了'MonetDB.R'並運行嵌入式(像'RSQLite')。有關更多詳細信息,請參閱https://github.com/hannesmuehleisen/MonetDBLite/blob/master/README.md – 2016-06-18 15:58:22
