Hi!
Generating two separate boxplots for a given set of data is no problem. But
when I combine them into one single diagram (with two boxplots), I get:
Error in sort.int(x, na.last = na.last, decreasing = decreasing, ...) :
'x' must be atomic
Calls: <Anonymous> ... boxplot.stats -> <Anonymous> -> sort -> sort.default -> sort.int
Execution halted
You can get the minimal example Org-mode on http://paste.grml.org/1036/
When I replace the line
boxplot(list(folders, tags),
with
boxplot(list(mfolders, mtags),
it works, though :-O
mfolders and mtags are lists in R and not imported via »:var«. Therefore I
guess this is an Org-mode/babel issue and not an R issue. What is my error?
Any help would be very cool!
PS: Org-mode version from git from yesterday

Org must convert tables to data.frames, which is a problem for boxplot():
,----- ?boxplot -----
| x: for specifying data from which the boxplots are to be
| produced. Either a numeric vector, or a single list
| containing such vectors.
`-----
So, you need to pass a list of /vectors/, not a data.frame. Here's
what's going on:
#+begin_src R
> str(folders)
'data.frame': 10 obs. of 1 variable:
$ V1: int 14 14 15 18 18 19 20 21 22 23
> str(mfolders)
num [1:17] 4.3 3.72 5.1 4.03 5.7 ...
> str(tags)
'data.frame': 15 obs. of 1 variable:
$ V1: int 1 3 3 3 3 3 4 4 4 4 ...
> str(mtags)
num [1:15] 3.95 4.25 5.22 6.2 5.27 ...
#+end_src
So... folders is a data.frame with one numeric vector, V1. Same for
tags. For mfolder and mtags, you created a vector, not a data.frame.
Try this to pass the vectors from each data.frame:
#+begin_src R
boxplot(list(folders$V1, tags$V1),
names=c("one", "two"),
xlab="boxplot12",
ylab="numbers",
pars = list(boxwex = 0.3, staplewex = 0.5,
boxfill="lightblue"))
#+end_src
That should work!

Great explanation, I understand what I did wrong, and it works now.
Thank you very much!
