Dear R-users, I'm encoutering some problems with the qcc()-function. When there are more than 25 replicates per "sample" the estimate for the standard deviation becomes NA, implying that nothing is plotted (error message: "Error in plot.window(...) : need finite 'ylim' values") On the forum I found a way to work around the error message, but this does not

Dear, We are trying to determine the (one-sided) CI for the coefficient of variation in a small sample (say n = 10), with mean 100 and standard deviation 21. It appears though that the R-function ci.cv() and our simulation do not agree. The R-code: library(MBESS) n = 10 ci.cv(mean = 100, sd = 21, n = 10, conf.level = 0.9) U10.95 <- 0.3551754 ci.cv(mean = 100, sd = 21, n = 10, conf.level =

Hi all, I have imported xlsx file (Excel 2007) into R using the following scripts. *library(RODBC) * *setwd(".......") * *query <- odbcConnectExcel2007(xls.file = "GI 2010.xlsx", readOnly = TRUE) dat <- sqlQuery(query, "select * from [sheet1$]", as.is = TRUE, na.strings = "exp")* *dat* contain one column consisting of intergers and characters

Hi list, By the entire last 2 weeks I was looking for a way to directly import xlsx files to R in a Linux OS (Ubuntu 9.04). I already read the R Import/Export guide, and I know how to use gdata to import xls files and read.table to import .csv. My problem is that all data that I receive is in the xlsx format, and I have to convert all the files to xls. Well, when I was using Windows Vista OS,

Hi List, just to know if the issue is only a problem of mine or if it is a general issue due to the new MS Office pack. I'm using R 2.11.1 32 bits in a Windows 7 x64 with the MS office 2010 x64 installed. I can import .xls files normally (the same way I did with my Excel 2007 32 bits). But the function odbcConnectExcel2007 isn't able to import .xlsx files now that I have the new version of

I am reading dates in Excel2007 into R. Here are the functions I used: library(RODBC) channel<-odbcConnectExcel2007("myfile.xlsx") tmp<-sqlFetch(channel,"1",as.is=T) The dates in myfile.xlsx are all in this format: mm/dd/yyyy. But when I read it to R, some columns look like "yyyy-mm-dd 00:00:00", some columns look like "yyyy-mm-dd", and some

I have come across the following situation when using the function pt which calls the student t distribution function. I simulate data from a normal distribution and fit the student t. The estimated degrees of freedom gets larger at each iteration and there is no convergence. It seems there should be some mechanism where it switched to a normal distribution when the degrees of freedom gets

Hi all, Apologies if I violate any posting etiquette - this is my first submission to the R mailing list. I regularly use 'odbcConnectExcel2007' (from package 'RODBC') to read data from named ranges in excel workbooks into R. I recently received the following error message when attempting to set up a connection channel (i.e. ch1 <- odbcConnectExcel2007('path to excel 2007

Hi sorry if this is really basic but I am just starting on R. Can anyone point me at how to write R objects into Excel 2007 files. I have seen how to set up a connection to a file through odbcConnectExcel2007(xls.file, readOnly = FALSE, ...) but it doesn't say anything on how to write data Thanks _____________________________________________________________________ The

I tried creating a .xlsx file using odbcConnectExcel2007 and adding a worksheet with sqlSave. This seems to work, I am even able to query the worksheet, but when I try opening the file in Excel I get the following message: "Excel cannot open the file 'test.xlx' because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file

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

Apologies if this is already answered elsewhere, but I could not find the answer searching the archives. I am trying to bring my data in from an .xlsx file. The data of interest is an n x m array, but it is preceded with ~2 columns and 30 rows of instrumental "information." An abbreviated example (cols denoted with "," for this example: Subject , 01 wavelength, 400 (30

RExcelInstaller_2.0-15 installs RExcel, an add-in for Excel, which connects R and Excel. RExcel allows to transfer data between R and Excel, writing VBA macros using R as a library for Excel, and calling R functions as worksheet function in Excel. RExcel integrates nicely with R Commander (Rcmdr), turning R Commander's menus into Excel menus. It comes with a comprehensive set of example

Hi community. I'm fairly new to R and have a basic question. When I try to install RExcel with the code: install.packages("RExcelInstaller", "rcom", "rsproxy") I get the message below: Warning in install.packages("RExcelInstaller", "rcom", "rsproxy") : 'lib = "rcom"' is not writable Error in

Dear Adrian, I would like to export a quite large matrix from R to Excel (40 columns, 257 597 rows). After 10 minutes of work, I get the following error message: Error in .jcall(row[[ir]], "Lorg/apache/poi/ss/usermodel/Cell;", "createCell", : Java Exception <no description because toString() failed> This is the code I used: write.xlsx(wvs19812008hm,

Hi Adrian, dat=data.frame(matrix(0,3,3)) write.xlsx(dat,"z:/dat.xlsx",sheetName="sheet1",append=F) write.xlsx(dat,"z:/dat.xlsx",sheetName="sheet2",append=F) The above code works and creates new worksheets. But if I want to append to an existing worksheet I seem to get an error.

Hi, I am trying to connect to an Excel2010 file while another user is entering data. (Obviously it would be better to set up a SQL database, but this is not an option at this point.). Typically we are not working on the same sheets. However, if possible I like to read the most current excel file into R. RODBC works great as long as the other user has not open the file. I tried: channel <-
