Hi! I'm manipulating XLSX data using RODBC, however a limitation which appears to be driver based is that you can't clear or drop sheets from the XLSX files, as per the following example: > library(RODBC) > xlsx<-odbcDriverConnect("DRIVER=Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb);DBQ=c:\\documents and settings\\desktop\\testxlsx.xlsx; ReadOnly=False") >

Hi to all. I have a problem to connect to an Excel database using RODBC. Namely, I am using 64-bit R 2.14.0, under Windows 7 and I tried following: library(RODBC) > channel <- odbcConnectExcel("results.xlsx") Error in odbcConnectExcel("results.xlsx") : odbcConnectExcel is only usable with 32-bit Windows # ok this is clear why it doesn't work > channel

I have some questions about the RODBC package. library(RODBC) # required for those who want to repeat these lines 1st, I noticed that the following sequence does not work: channel <- odbcConnextExcel("test.xls") tables <- sqlTables(channel) name1 <- tables[1, "TABLE_NAME"] # this should be the name plan1 <- sqlFetch(channel, name1) # bang!

Hi, I'm attempting to use the RODBC package on Windows Vista to import an excel spreadsheet. The spreadsheet has three worksheets the last of which is blank. Following an example in Phil Spector's book (p. 34), after creating a connection named con I did the following: > con RODBC Connection 3 Details: case=nochange DBQ=c:\temp\test.xls DefaultDir=c:\temp

Hi, everyone, I try to run as follows: Z>library("RODBC") Z>cnct<-odbcConnectExcel("Forbes2000.xls") Z>cnct RODB Connection 1 Details: case=nochange DBQ=C:\Program Files\R\R-2.5.0\Forbes2000.xls DefaultDir=C:\Program Files\R\R-2.5.0 Driver={Microsoft Excel Driver (*.xls)} DriverId=790 MaxBufferSize=2048 PageTimeout=5 Z>sqlQuery(cnct, "select

Hi, I am a new R user and am trying to construct a palaeoenvironmental transfer function (weighted averaging method) using the package rioja. I've managed to insert the two matrices (the species abundance and the environmental data) and have assigned them to the y and x values respectively. When I try and enter the 'WA' function though, I get an 'Error in FUN' message (see

I have a small Excel data file with two columns of character variables, one column with a numeric variable and three rows. One of the character cells is blank and one of the numeric cells is blank. I read the data file with the following code: library(RODBC) channel <- odbcConnectExcel('u:/test.xls') sqlTables(channel) s1 <- sqlFetch(channel, "Sheet1")

hello all i have a quick question. i have been using the RODBC library (trying to read Excel data into R but i am doing this by using Rexcel. this is probably not the correct forum - sorry for this). my code is shown below: Sub A() 'start the connection to R Call RInterface.StartRServer RInterface.RRun "library(RODBC)" RInterface.RRun "A =

Hi folks, Win 7 64bit R 2.12.0 32bit Problem in reading Excel spreadsheets (the text file, research_databaseI.xls, was download on Internet) > data=odbcConnectExcel(file.choose()) > sqlTables(data) TABLE_CAT TABLE_SCHEM 1 C:\\Users\\satimiswin764\\Documents\\research_databaseI <NA> 2

Hola, Pensé que esto iba a ser trivial en R, pero me estoy encontrado muchos con mi problema en internet, y que las soluciones ofrecidas no terminan de funcionar. Estoy intentando leer un fichero .xls en ubuntu con los siguientes paquetes y nada: require(RODBC) conn = odbcConnectExcel("madrid.xls") # open a connection to the Excel file sqlTables(conn)$TABLE_NAME # show all sheets df =

essai <- odbcConnect("ORESTE_prod", uid="osis_r", pwd="12miss15" ,case="oracle") > sqlTables(essai)$ORESTE ... 1315 <NA> ORESTE S_PROFESSIONS_OLD TABLE <NA> 1316 <NA> ORESTE S_PROVENANCES TABLE <NA> 1317 <NA> ORESTE

Why the result is coming as NULL. Can anyone help. I want to find the outliers for a reference setwd("D:/AZ") library("RODBC") cdb_cnct <- odbcConnectExcel("Book1.xls") cdb_frame <- sqlFetch(cdb_cnct, "Sheet1") odbcClose(cdb_cnct) rm(cdb_cnct) x<- cdb_frame$Publication >=1990 & cdb_frame$Publication <=2012 invalid <- cdb_frame[!x,

Hi All, I'm using R 2.11.1 on 64 bit windows XP. The little function I wrote below I use often to import the first 1001 lines in an excel sheet to R. This works fine on the 32 bit version of R but fails on the 64 bit [both on the same machine, using the same function, importing the same .xls file]. The message from 64 bit R is: Error in sqlTables(channel1) : first argument is not an

Hi, i'm trying to read some data from excel files but it seems that neither xlsReadWrite nor sqlFetch (RODBC) doesn't like the format (Excel 5.0). When i open the file in Excel and save it in a new format Excel 97 -2003 everything works fine. Is it possible to use ODBC connection to open old format files, or i guess i will have to open and save every file in Excel in new format, which

Hello! I have no problem reading Excel files (each worksheet in the file is a "table" which can be read - at least in my case). What I would like to do is to read such a table, change it (just the contents, not the format) and write it back, and this I can not do. I am getting the following error messages (3 slightly different attempts): > sqlSave(con, x, tablename =

I have probably an old question. I have R.3.0.1 installed in 64 bit windows 7. The odbcConnectExcel in RODBC library does not work. Tried odbcConnectExcel2007 still does not work. Any ideas. Thanks Melissa<-sqlFetch(odbcConnectExcel2007("F:\\Cotton2012\\validation.xlsx"),sqtable = "Sheet3", + na.strings = "NA", as.is = TRUE) Error in

Hi List, I used to access a Paradox database using RODBC, but since last week I am not able anymore to fetch any table which has a name longer than 11 or 12 characters. Here is the the pattern of my code, nothing spectacular: library(RODBC) channel2<-odbcDriverConnect('DSN=xxx') #table names with up to 11 characters still work sqlFetch(channel2, 'abcdefghijk') #table names

I gather from reading the back-issues of r-help that it should be possible (modulo a number of caveats) to read an excel (yuck!) file into R using RODBC. I have obtained and installed ODBC and the RODBC package, but cannot for the life of me figure out how to go about it. Can anyone give me a simple recipe? I have an excel file on cdrom, say: /mnt/cdrom/melvin.xls I have started R and loaded

The first column in my Excel sheet has mostly numbers but I need to treat it as character data: > library(RODBC) > channel <- odbcConnectExcel("U:/efg/lab/R/Plasmid/construct list.xls") > plasmid <- sqlFetch(channel,"Sheet1", as.is=TRUE) > odbcClose(channel) > names(plasmid) [1] "Plasmid Number" "Plasmid"

Hola, @javier, me gustaría no tener que hacer nada de forma manual, ni por fuera de r, rstudio. Es decir, el típico comando de linux que me convierta de xls a csv prefiero no usarlo. Me gustaría hacerlo todo desde R. @jorge -> Con RODBC me salta -> Error: could not find function "odbcConnectExcel" Lo que creo que es inevitable en Ubuntu
