Feature Request: Multiline Comments
...to include multiline comments like
/*
acomment
*/
?
This way I can integrate emacs org-mode with my R code, so that I can
have a table of contents,
section folding, html-output of source etc.
e.g
/*
* Display Code
*/
#+BEGIN_SRC R
foo <- function(...){
stuff
}
#+end_src
and so on .
Thanks

Lines between panels in lattice
...ve.to(unit(0.72,"native"),unit(3.8,"native"))
seekViewport("plot1.panel.1.1.vp")
grid.line.to(unit(1.2,"native"),unit(3.5,"native"))
However, I can see the line in the bottom panel, but nothing in the
top. Is there some
clipping going on?
Thanks

Package is loaded but functions are not exported
...^\\rh")
On R-2.8 (Linux, 64), upon loading the package I have the rh functions present.
On R-2.10, Mac OS X, (32 bit), it builds, loads, but the functions are not
loaded, i.e the only function is rhyper (which is not from my package).
Is there something wrong with my package setup?

eval using a environment X but resultsin .GlobalEnv
...nment V.
I do this via
eval(E,envir=V)
however all assignments end up in V. I would like the results of
assignments in E to end up in the .GlobalEnv ? Or at least the calling
environment.
Is there a quick way to this instead of iterating over all objects E
and assigning into .GlobalEnv?
Thank you
Saptarshi

Y-axis label on the right hand side in lattice?
Hello,
Is there a way to add ylab on the right hand side also (in lattice)?
Different from the left hand side?
Cheers

In C, a fast way to slice a vector?
...,
PROTECT(sr = R_tryEval( .... ))
sr is a RAWSXP vector. I wish to return another RAWSXP starting at
position 13 onwards (base=0).
I could create another RAWSXP of the correct length and then memcpy
the required bytes and length to this new one.
However is there a more efficient method?

Lattice and Axis height
...e bottom strip of every panel is grid viewport with a
height, there could be an option to set the height to 0 when I'm the
top panel.
Or maybe like par.strip.text I could set it to a vector equal to the
length of the panels, alternating (Draw,DontDraw,Draw,....)
Is this possible?
Regards
Saptarshi
P.S I'm essentially passing dummy variables to xyplot and for each
value of the dummy variable pulling in data from a postgres database
setting my limits for each panel based on the pulled in data and
plotting that.

Writing a Long across the network?
...sending struct.pack( "!q", value)
However, I have tried this
writeBin(length(x),con=conn,endian="big") #conn opened in binary
But the response on the server side is wrong, eg. 1 is received as
4294967297
How do I then write long across the network from R?
Thank you

Embed R, and provide a function to user scripts
...##user supplied expression that is given to me
x<-1
boo(x)
One way is to create a library with function boo that performs .Call to boo,
but is there a way that I can do something like
ainstall("rboo", boo)
and calls to rboo in the language will be sent to 'boo' ?
Thank you

Return a list from a .Call but segfaults
...e that message2rexp is to blame.
Yet, when i replace the code with R code, that is using readBin and
only calling calling C(to call message2rexp) to deserialize a raw
vector, I get no such error.
There is something I'm missing , could someone tell me where?
Thank you for your time

time of serialization
...em.time(y <- lapply(x,function(r){
system.time(serialize(r,NULL))['elapsed']
}))
> sum(unlist(y))
18.812
> z
user system elapsed
494.144 0.041 494.247
So, the entire lapply takes ~26 times longer than the sum of the
individual operations.
Have i missed something?

A question about multiple(?) out of order ReleaseObject
...ssociated with 'v'
Is (1) and (2) correct?
I have not used R_protect/unprotect, because if I return from cfunc without
the equivalent number of unprotects, i get 'unbalanced stack' warnings. I'd
rather not have to worry about that because i intend to balance it later.

Splitting a lattice stripplot across several pages
...of
packets in a connection. Roughly
stripplot(totpacks~portnum,data=network)
Due to the large number of server ports in my dataset, the y-axis
labels overlap so I would like to split it across several panels(1
panel per page) with about 25-50 per panel.
Is there a way to do this?
Regards

Transferring R to another computer, R_HOME_DIR
...R_HOME_DIR. I have the need to rsync
the entire folder below /usr/lib64/R to another computer into another
directory location. Without changing the R shell script, how can i
force it read in R_HOME_DIR?
Or maybe i misunderstood the bash source?
(Note, i cannot recompile on target machine)
Cheers

1. I also realize Rscript will not work (i think path is hard coded in the
source)

Remembering a value in multiple calls of a function
...sn't this environment lost?
Also the print displays GlobalEnv, yet the globalenv does not have any
mention of startgiven.
This code was inspired from and old issue of RJournal , but I'm not
sure how this works.
I'm not sure how this works and an explanation would be helpful.
Thank you
Saptarshi
getN <- function(start){
startgiven <- start;
incr <- function(n=NA){
print(parent.frame())
if(!is.na(n)) startgiven<<-n
startgiven<<-startgiven+1

Multidimensional Integration over arbitrary sets
...on the other e.g integrate f(x,y)=x*y over {x,0,1} and {y,x,1}.
i.e \int_0^1 \int_x^1 xy dydx
I checked adapt but it doesn't seem to help here. Are they any
packages for this sort of thing?
I tried RSitesearch but couldn't find the answer to this.
Many thanks for you help.
