Hello,
I'm *guessing* that this is more likely an issue of R than of org-mode.
Have you tried tangling the code and simply running the scripts through R?
Essentially, the as.matrix function call is returning a character
matrix, which could mean your object 'alldata' has some factors instead
of numeric columns.
R 2.7.1 is, by R standards, ancient, so it would not surprise me a bit
if the differences were because of that old version.
Unless you can show that this is somehow org-mode related, I'd construct
a reproducible example and ask R-help. In any case, reproducible
example will help in solving the problem.
Good luck!

I have had a similar problem and I traced it back to the presence of horizontal lines in the source table. The two ways that I have dealt with the problem are to either not have horizontal lines in the table or use some R stuff to clean things up. For example, suppose that I have the following table
#+TBLNAME: mytbl
|column1|column2|
|------------|-----------|
| 45 | 34 |
| 77 | 56 |
when I send that to R, it will treat everything as character due to the horizontal line. The following R snippet will clean it up and recast everything as numeric.
#+BEGIN_SRC R :var tbl=mytbl
names(tbl) <- tbl[1,] #renames the variables from V1, V2 etc to what they should be
tbl <- tb[-1,] #gets rid of the first row that had the errant variable names
for (i in 1:ncol(tbl)){
tbl[,i] <- as.numeric(tbl[,i])
} # the for-loop goes through each column and recasts it as a numeric variable instead of character.
#+END_SRC
of course, if you have a column of text in the first column (or any column for that matter) you need to adjust your for-loop accordingly.
I hope this helps.

Which version of org-mode are you using? I do not see what you
claim to see.
What do you get when you run the following:
#+TBLNAME: mytbl
|column1|column2|
|------------|-----------|
| 45 | 34 |
| 77 | 56 |
#+BEGIN_SRC R :var tbl=mytbl :results output
str(tbl)
#+END_SRC
I get the following, which looks right to me.
#+results:
: 'data.frame': 2 obs. of 2 variables:
: $ column1: int 45 77
: $ column2: int 34 56

Hi Seb,
The problem is that Org has not automatically recognised that you want
the first row to be treated as column names. The reason is that your
table contains multiple horizontal separator lines. So for this table,
you must use ':colnames yes' to tell Org that your first row contains
column names. See sections 14.8.2.12, 14.8.2.13 and 14.8.2.14 in the
manual.
As Erik pointed out, using str is a very good way to investigate your
data structures. Notice below that your column names have become the
first row of the data frame, and as a consequence the columns of the
data frame have been force to character rather than numeric:
--8<---------------cut here---------------start------------->8---
#+srcname: barplot-investment(ptable = investissement-2010-2013)
#+begin_src R :XXX-file 1-01-investissement-2010-2013.png :exports none :session :results output
str(ptable)
#+end_src
#+results: barplot-investment
:
: 'data.frame': 5 obs. of 5 variables:
: $ V1: chr "" "RFO" "RFO réseau structurant" "Équipements" ...
: $ V2: chr "\\s{Année 2010}" "2596376.3" "3804467.0" "1000000.0" ...
: $ V3: chr "\\s{Année 2011}" "1500000.0" "6534066.0" "150000.0" ...
: $ V4: chr "\\s{Année 2012}" "500000.0" "3804467.0" "50000.0" ...
: $ V5: chr "\\s{Année 2013}" "500000.0" "0.0" "50000.0" ...
--8<---------------cut here---------------end--------------->8---
However, if we use :colnames yes then we have
--8<---------------cut here---------------start------------->8---
#+srcname: barplot-investment(ptable = investissement-2010-2013)
#+begin_src R :XXX-file 1-01-investissement-2010-2013.png :exports none :session :results output :colnames yes
str(ptable)
#+end_src
#+results: barplot-investment
:
: 'data.frame': 4 obs. of 5 variables:
: $ X : chr "RFO" "RFO réseau structurant" "Équipements" "Total (HTVA)"
: $ X.s.Année.2010.: num 2596376 3804467 1000000 7400843
: $ X.s.Année.2011.: num 1500000 6534066 150000 8184066
: $ X.s.Année.2012.: num 500000 3804467 50000 4354467
: $ X.s.Année.2013.: num 500000 0 50000 550000
--8<---------------cut here---------------end--------------->8---
And in this case you probably want ':rownames yes', which will mean you
no longer need the -1 in the indexing expression in your R code.

Thanks a lot for your detailed explanation. It helped a lot.
