Hi,
I have a code block like this
#+NAME: users_per_month
#+HEADER: :results append
#+BEGIN_SRC sh :dir /root@sadmin:
sacct=/cm/shared/apps/slurm/current/bin/sacct
for y in {2014..2014}; do
for m in {03..04}; do
month=$y-$m
first=$y-$m-01
last=`date -d "$first + 1 month - 1 day" +"%Y-%m-%d"`
n=`$sacct -S $first -E $last -o user -X -n | sort | uniq | wc -l`
echo $month $n
done
done
#+END_SRC
which produces something like this
#+RESULTS: users_per_month
| 2012-01 | 1 |
| 2012-02 | 10 |
| 2012-03 | 100 |
| 2012-04 | 1000 |
I'm using append because the generation of a datapoint takes a while.
I'd like to plot the data with something like:
#+NAME: plot_users_per_month
#+HEADER: var data=users_per_month
#+HEADER: :results output graphics
#+HEADER: :file ./users_per_month.pdf :exports both
#+HEADER: :session *r*
#+BEGIN_SRC R
library(ggplot2)
bar_colour <- "#69B4D8" # steely blue
month <- data$V1
users <- data$V2
df <- data.frame(month,users)
p <- ggplot(df,aes(x=month,y=users)) +
geom_bar(stat="identity",alpha=0.5,fill=bar_colour) +
xlab("date") +
ylab("users")
p
#+END_SRC
However, this is just generating a plot of the data generated by the
source block and not of the total results table.
Can I give the results block a different name to the source block, so
that I can refer to it directly, or should I be doing something
completely different?
Cheers,
Loris

I believe so: the source name ties the source block to the same named
result block - that allows the source block to find the result block
and modify it appropriately. The results block can be named and then
that name can be used in the plotting block, e.g.
--8<---------------cut here---------------start------------->8---
#+name: foo
#+BEGIN_SRC sh :results output table append :var n=5
for x in $(seq $n)
do
echo $x $(expr $x \* $x)
done
#+END_SRC
#+name: foo_results
#+RESULTS: foo
| 1 | 1 |
| 2 | 4 |
| 3 | 9 |
| 4 | 16 |
| 5 | 25 |
#+NAME: plot_foo_results
#+HEADER: :var data=foo_results
#+HEADER: :file ./foo.pdf :exports both
#+BEGIN_SRC gnuplot
plot data
#+END_SRC
--8<---------------cut here---------------end--------------->8---

Oh, that's rather obvious *blush*. I suppose I was thinking that the
whole results block is generated and it didn't occur to me to just give
it a name.
Thanks,
Loris
