Hello Could you please suggest a way to find out the r square values for each independent variable while using "lm" for developing a multiple linear regression model. Thank you avneet "I have no data yet. It is a capital mistake to theorize before one has data.

Hello R-Help, is there any way of using the RODBC Package on a Mac OS X System? If yes, what do I need to get it running. Concerning these issues, I am pretty unexperienced, so please state any step necessary. The actual problem is accessing data in Excel- files. (unfortunately no alternative way of entering the data). I already installed the Package, but it says the following: > versuch

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

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

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

Hi I am using package RODBC version 1.0-1 under R version 1.7.1 on Windows XP Pro. I am having problems writing a new table to an (Excel) database using sqlSave. I connect to an empty Excel spreadsheet using odbcConnectExcel (which, I believe, uses the Microsoft Excel Driver DSN). Then I try and save a new table to the database(spreadsheet) using SqlSave, but obtain an error message. Below is

Hello, I have some problems with RODBC and Excel in Win98 I am using R 1.6.2 and just upgraded RODBC to the last version on CRAN. I have an Excel file with columns Number, Name, Sex, Age, FEV1 on Sheet 1 and Number, Age, FEV1, Name, Sex on Sheet 2.

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 =

Version 1.2.6 of RODBC is now on CRAN. This has a number of bug fixes and many workarounds for ODBC driver quirks--I've set up further testbeds for SQL Server 2008, Oracle and DB2. More visibly, the documentation has been expanded in several ways, in particular in collecting together advice on using 'schemas' and 'catalogs' in the ?RODBC overview. There is also a test

Dear R users, I've learned today about RODBC package in order to import xls file to dataframes and export the dataframes to xls files. However I have some problems. Please excuse me if these are basic but as I said, I've just begun with this package. Also this email is quite long, but everything is related, so I don't think it would be better to split it. Moreover, there's a

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"

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!

Dear all, I'm reading data via the RODBC connection using odbcConnectExcel. I use sqlFetch(channel, "sheetx") to identify the correct tab. It appears to read the data without any problems. However, when I exact a portion of data - the row number specified is 1 less than in the actual excel file and it can't read any columns after the 94th column. Can someone help me? TIA Dave

Hi, all, I'm trying to use RODBC to read data from Excel. However, I'm having trouble converting missing values to NA and rather perplexed by the output. Below illustrates my problem: ## DATA - copy to Excel and save as "tmp.xls" ## tmp.xls!Sheet1 x 0.11 0.11 na na na 0.11 ## tmp.xls!Sheet2 x 0.11 0.11 na na na na 0.11 ## R Code read.xls <- function(file, sheet =

L.S. I am trying to get data from an excel sheet using the RODBC library, quite like the example on page 34 of the 'Data manipulation with R' book written by Phil Spector. It seems very straightforward, yet I get the same error everytime I try it, with different excel sheets and trying to tweek the code a bit. This is what I do: library(RODBC) sheet='X:\\example.xls'
