Dear All, How do I read in multiple data frames or matrices in a loop, e.g. for (i in 1:n) { channel <- odbcConnectExcel("filenames") file[i] <- as.data.frame(sqlFetch(channel, "sheet")) } I would like file[i] to be the name of the data.frame (i.e. file[1], file[2], file[3],...etc) rather than a vector. Thanks in advance for any help. Dave

Hi, I am a new R user and am trying to construct a palaeoenvironmental transfer function (weighted averaging method) using the package rioja.

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

I'm using the RODBC library to read in an Excel file using the odbcConnectExcel function. I can read the Excel data prefectly, however all my character variables get converted to factors when using my.data <- as.data.frame(sqlFetch(channel, "Sheet1")) I've tried using my.data <- as.data.frame(I(sqlFetch(channel, "Sheet1"))) but this creates just

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.
