Hello...

I get pretty much the same error message for both functions: odbcCloseAll() produces: Error in .Call("RODBCCloseAll", PACKAGE = "RODBC") : "C" function name not in DLL for packag...

R crashes when using the RODBC Package
..., but if I put a loop around the code so that I fetch data from a different source table, and then save it again to a different destination table, the code crashes. It is either the final sqlQuery or sqlSave queries. I have no idea why it is crashing. As an aside, I also have trouble with the odbcCloseAll() command - R tends to crash with that, also. I'm running this on Windows XP, Access 2003, R version 2.7.2 Any insights would be greatly appreciated! The condensed version of the code is below. # import the libraries library(RODBC) # Close any existing connections odbcClos...

The script connects, reads and writes data but when it comes to odbcCloseAll() it crashes and hangs fo...

.Rprofile and RODBC
...y but R 2.0 does not. How do I get R 2.0 to do this? 2) The following function no longer works in R 2.0 but continues to work in R 1.9: getExcel <- function (x) { invisible(require(RODBC)) x <- sqlFetch(odbcConnectExcel(file.choose()), "exceldata", na.strings = "NA") odbcCloseAll() #closes the connection invisible(edit(x)) } I use this function to choose an Excel file and open it using an ODBC connection. Why does this not work now? Thanks in advance for you help. ~Nick

problem with looping on sqlSave()

Elements 2 and 3 have the same number of columns; the problem persists in that case. Thanks a lot for your help Ivan

RODBC to import/export xls files
...uld be great if I could just import the 1st sheet into the dataframe. - to export I do this (from Tal Galili's solution earlier today): xlsFile <- odbcConnectExcel("file", readOnly=F) save2excel <- function(x, t.name) sqlSave(xlsFile, x, tablename=t.name, rownames=F, addPK=T) odbcCloseAll() It also works great, but how can I append lines? This function allows me to append new sheets in the file, but I would also like to append new lines of data onto one of the sheets. How can I do that? - The last problem: I would like to export a dataframe, but I get this error message: > sa...
