Hi Rob,
Andreas' post answers your specific question.
In your situation, I typically don't run through a csv file, but just
write the R script so the data frame is returned to the Org mode buffer
as the result of the source code block.
As for the translation of column heads, see the ascii package for R,
which has a print() routine that recognizes Org mode as a type of
output, and which has facilities for formatting column names.
Here is an example from some work in progress that uses a session:
#+property: exports results
#+property: colnames yes
#+property: session *adzes*
#+name: lda-mid-z
#+header: :results output org
#+begin_src R
y <- edxrf[edxrf$lab=='UH-Hilo',]
fit <- lda(as.factor(site) ~ rb_ppm + sr_ppm + y_ppm + zr_ppm + nb_ppm,
data=y, na.action="na.omit", CV=TRUE)
adzes <- y$site=='unknown'
cap <- "Assignment of unknowns to sources"
z <-
ascii(cbind(BPBM=y$bpbm[adzes],round(fit$posterior[adzes,],2)),header=T,include.colnames=T,caption=cap)
print(z,type="org")
rm(y,fit,adzes,cap,z)
#+end_src
#+RESULTS: lda-mid-z
#+BEGIN_ORG
#+CAPTION: Assignment of unknowns to sources
| BPBM | Haleakala | Kilauea | Mauna Kea | Nu`u | Pololu |
