So if the people you have to deal with are into astrology you should
learn astrology?
Flame wars are usually vituperative, often entertaining, and
occasionally productive. Excel is good for accounts and for taking
notes, sometimes for back-of-the-envelope calculations. It is not so
suitable for statistics and its formulae can be incomprehensible when

As far as I understand, changing the format changes
the way data is displayed by Excel but this does not
change the data itself - if while reading the data
Excel decided that it was a date, it is being

If you format the column as "Text", you won't have this problem. By
leaving the cells as "General", you leave it up to Excel to guess at
the correct interpretation.
You will note that the conversion to a date occurs immediately in
Excel when you enter the value. There are many formats to enter
This is very consistent with Microsoft's philosophy:
they know better than you what you want to do.

A common process when data is obtained in an Excel spreadsheet is to save

I read excel spreadsheats into R often using the RODBC package. I like
being able to manipulate my data in excel then import it directly into R
without saving as text. I use a windows xp machine and an older version of
R (1.9.1). Assuming you have a worksheet in melvin.xls named "data", here

Success! Tobias Verbeke's kind suggestion of read.xls from the
gdata package (from the gregmisc bundle) works like a charm.
It's perl based, so no problema on Linux.
The R community is wonderful!

I found the reading of whole sheets somewhat unsafe, so I always create a named
range (here: data) including header and do the following.
Never had problems with this.
channel = odb
The following works for me under WinXP Pro to create "myframe" as a
data frame:
library(RODBC)
z <- odbcConnectExcel("c:/myfolder/mydata.xls")
myframe <- sqlFetch(z, "Sheet1")
close(z)
