Hi, I have tried to load a file originally from Excel, via csv, text and clipboard today.
When I succeed I cannot change the format from "factor", and when I try to convert it to numerical it only gives the position of the "factor-group", not the real value in the column?
Any quick suggestions?

Importing multiple worksheets from one Excle/ csv file into R
Dear R experts,
I am trying to import some data from some Excle files into R. My Excle file
contains about 50 sheets.
One solution I can think about is to convert my Excle file into csv file
first and then load data into R using 'read.csv'.
But it seems to me that 'read.csv' only supports reading one sheet (or 'one
file') each time, so that seems I have to create 50 csv

Decoding via API from a single FLAC file using a cue sheet
Hello,
I have currently many of my CDs ripped to FLAC to replay them from the
computer. In most cases, there are single files for each track on the
CD. I like the idea to rip the CD to a single track and add a cue sheet
to the metadata which was recently discussed on the list.
How would I access specific tracks using this approach by means of the
FLAC (or FLAC++) API in my own decoder

importing selected rows and columns from text
I read through the import/export manual a few times and did not see this
mentioned and checked the archives as well. I am dealing with data sheets
generated by Eprime (a software package for generating experimental
psychology paradigms) that output subject responses in a proprietary Edat
file format. All individual subject response spread sheets can be merged to
form one long file of all

Error when writing to Excel files using the packages xlsx and xlsx2
Dear group,
I am working on a rather big project where the output data frames have
dimensions of 3000 x 15 or greater. We are using xlsx and xlsx2 to write the
data.frames to Excel sheets.
Since recently we get the following error, when trying to write the data
frames to the excel sheets:

OT: batch processing XLS files to CSV
Dear R gurus, particularly those of generous M$ tolerance and diverse
gifts and knowledge!
I have an interesting challenge that I will end up crunching in R
involving service usage by patients. Maybe I can do all of it in R but
I can't see how yet.
My situation is that our IT Department can give me loads of XLS files
about patients one of our services have seen. The are one per patient

numbers and decimal points
I have a question for our European readers: how common is it to use
commas as decimal points in spread-sheet and statistics applications?
Is it an inconvenience to require that all data use a period as decimal point?
(i.e., 3.14159 rather than 3,14159).
We're trying to make our program as foolproof as possible, and would
prefer not to give users a chance to have commas as both decimal

merging to data.frames whose columns are different but follow a pattern.
Hi,
I'm working with panel data from the Swiss Houshold Panel (SHP). The data i
got came in the following way:
1.) 12 *different* /individual/ files - one for each year .
2.) 12 *different* /houshold/ files - again: one for each year
Each file came in the SPSS format (.sav). I implemented all the files in R

RExcel doesn't get active dataset
Hey everyone
When I try to 'get active dataframe' from the context menu in excel using Rcmdr menus in excel, only the header and first row of data gets copied to the excel spread sheet. No clue why this is happening. I followed the instructions from 'R through Excel' pg 25-26. I'm using excel 2010, Rcmdr v 1.6-0 and R 2.11.1.
Much appreciate any help

Complicated question
I'm not sure if this is the right place to post this, but here goes. I
just put together a PDC using Samba. I have given users the ability to
change their passwords (once every 7 days) if they wish. I used to keep
a list of usernames and passwords in a spread-sheet, so I could keep
track of the servers that I needed to update with the correct password
if anything changed. That being said.

using eval-parse-paste in a loop
R-helpers
I have 120 small Excel sheets to read and I am using
library(xlsReadWrite): one example below.
I had hoped to read sheets by looping over a list of numbers in their
name (eg Book1.xls, Book2.xls, etc).
I thought I had seen examples which used eval-parse-paste in this way.
However, I have not been able to get it to work..
1. is this a feasible approach?

RCOM Package
Hi list,
I just installed the rcom package and tried to read/give out some values
from/to Excel. Altogether it works great... but nevertheless I don't know
how the syntax works or in other words: "Which command needs which
parameters?"
Is there somwhere a manual about this package with good examples? I've read
the Package description... but there are not really good
