[R] 2nd R Console
Hi, I was reading a thread: [R] 2nd R console and had a similar question regarding having more than one R console open at a time. However, my question differs from that of the thread: Is it possible, or is there a wrapper that will allow one, to open an arbitrary number of R consoles which access the same R session (all objects in that session, etc.). This would be R on linux accessed through a shell - kind of like using GNU screen multi-user such that people could work collaboratively on a given session. The problem with screen is that all commands are interleaved in the same terminal, which is confusing and does not allow access to the command prompt at the same time, rather it would be sequential. I know there will be why questions but it is useful in an academic environment. Basically we have a memory machine for large genomic analysis - and we could set that up as an Rserver, but this placing R into a multi-user engine is better suited for our immediate needs. Does anybody have thoughts on this?

Does anybody have thoughts on this? You could have a look at XMX (X-protocol Multiplexer). This is now rather old, and I think it has not been further developed for many years. http://www.cs.brown.edu/software/xmx/README.patch7 Basically, you would start XMX from one machine (A) networked to others (B,C,...), all running X-windows. in the startup, you designate which machines are to share the session, and what rights they will have. On machine A, and all designated machines B, C, ... , appears a window. This in fact acts like a screen emulator, with its own X session inside it. The A user then starts up a program (say R) in this window, and what A sees is mirrored on the other machines. If A has granted input privileges to the other machines, then users of B, C, ... can do things themselves, and the effects of their actions are mirrored to all the other machines. Thus, for instance, it would be possible for different users to take turns at entering commands into the R session, and so on, from their own machines. This is a much better way of arranging things, than having all the people queue up to take turns at sitting in the one and only chair! It is certainly useful in a classroom situation, and even in a one-to-one tutorial. For instance, I've used it in the past to teach programming and system management, sitting more or less beside the other person but at different machines. We would both, for instance, be editing the same program file, and either could initiate a program run with the current file. (Of course, what's technically called a race condition can develop here ... ). I've even envisaged the scenario where two people, one in England and one in the US, could simultaneously be editing a joint paper (you'd also need an independent communication channel as well, but that's no problem using a chat program). The one constraint with XMX (at least in the past, I'm not sure to what extent it may have been relaxed) which can limit its use is that it depends on fairly close compatibility between the X resources of all the different machines. It's best of they're identical (same screen resolution e.g. 1024x768, same colour depths on all screens, ... ). Otherwise it's liable to not establish the necessary connections, and only some machines can join in. However, in a computing lab environment, it may well be that all machines are compatible. Suck it and see! Hoping this is useful, Ted.

Re: [R] keyboard issue in R console
We can also say that in recent versions of R you have to choose deliberately to disable readline when building R. (This is made quite hard: I am currently building R on a brand new Solaris 10 system, and I had to work to get the right 64-bit libreadline linked in. Just having libreadline[-devel] missing is not enough.) I think Hao Liu needs to explain how he managed to do this, by giving the basic information asked for in the posting guide, e.g. - version of R - what is 'linux' here - how R was installed (from sources, RPM, .deb ) On Fri, 4 May 2007, Marc Schwartz wrote: On Fri, 2007-05-04 at 10:48 -0400, Hao Liu wrote: hi!

[R] Mac OS X: Clearing R Console screen
Hi all, I'm trying to figure out how to clear the console (screen) in the Mac OS X R console. Using ctrl-l does not work. I have also tried system (clear) but, I get TERM environment variable not set., I find this a bit strange because system(ls) and other bash commands work fine. When using R in Terminal or iTerm, the system(clear) works great. Any ideas on how to get the R Console to clear, or how to set the TERM variable? I see others have had similar issues but, can't seem to find the solution. Thanks!

But Brian did give you all you needed (even more I'd say) to
solve that !?!?
Please apologize if I use a bit frank language, but using R, you
*really* are expected to read the documentation which is written
pretty carefully {probably that's what some people don't like
about it and call confusing ??}.
Specifically, Brian said
BDR 200 columns will take far more than 250 characters. The help says
and then pointed you to the docu for options(width = .).
I think you need to reread that paragraph, particularly the word
'character' and then you will understand that your original
approach of using options(width = 250) can *not* be what you
want if your dataframe has 200 columns.

Thank you for your answer. When I set options(width=250) I still get
the same result when I print the data.frame on my Rgui console (R

an
error (?) message
[ reached getOption(max.print) -- omitted 3462 rows ]].
As Petr explains below (and Brian Ripley), you
*really* should use different means here ---
but I think this is the first time that the relatively new
option 'max.print' has hit R-help, hence one other hint, maybe
useful to the public:
Note that the 'max.print' option was introduced exactly for the
purpose of **protecting** the inadvertent user from a flood of output
spilling into his console/gui/..
(and apparently locking up R completely, we have even seen
crashes when people wanted to print dataframes/matrices/arrays
with millions of entries).
So, given the above message (yes, not an error),
why did you not try to read
help(getOption)
and look for the word 'max.print' there ?
-- if you really really don't want to follow the advice of
Brian and Petr, then say something like
options(max.print = 1e6)
Martin Maechler, ETH Zurich
For example if I have a data.frame with 4000 rows and 200
columns I would like to be able to use scroll bars in
Rconsole to investigate the whole data.frame.
Petr I am not sure if it is the best idea. You shall probably use
other
Petr means for checking your data frame.
Petr Try ?summary, ?str or if you really want to check all values in
data
Petr frame you can use
Petr invisible(edit(test))
Petr to open a spreadsheet like editor.

[R] Data.frame columns in R console
Hi R-users, A newbie question: assume that I have for example 30 columns in my data.frame named DF. When I print DF in R console I get columns that don't fit on the same row underneath each other. So how do I change the R console preferences so that the console does not wrap my data.frame columns? I want the columns to be printed next to each other, as in a normal table.

Re: [R] Data.frame columns in R console
?options, look for 'width'. I don't know what OS this in: the Windows Rgui has an option to set the width to the width of the console, but you can override it.

Re: [R] 2nd R console?

Re: [R] Console not found
Sounds like you have corrupted your Rconsole file. Fire up rterm and try ?Rconsole and/or read the rw-FAQ to find the file that it is use. It is not removed by uninstalling, and you do need to remove it. (The console settings have nothing whatsoever to do with memory settings.) Your matrices are not particularly large, BTW, provided you have 1GB or more of RAM. If you have much less, adding some RAM is the most effective way of using R.

See appendices B.1 and B.2 of the R-intro manual for all the details. In summary, R looks in Renviron.site, Rprofile.site, .Rprofile, .RData and Rconsole for startup information. (Where it looks is complicated; see the manual.) There are command line options to tell it to skip these; in particular, --vanilla tells it to skip all of them. I'd guess your problem is with Rconsole, because that's where the console settings are normally saved. Rename it to something else and your problems should go away.

[R] Cocoa GUI: pasting in R Console yields syntax error
I've recently upgraded to R-2.0.1 on a Mac running OS X 10.3+ I am using the new Cocoa-based GUI. Everything was working well for a while. In the middle of an R session, I started suddenly to have a problem where code copied from an open editor window and pasted into the R Console gives a syntax error. It doesn't matter what the code is. If the same exact text is typed into the console directly, I get no errors. I tried quitting the R session and restarting. The problem did not go away. I tried using a different editor, instead of the built-in editor. After opening the file with my R code in it in AlphaX instead of the built-in editor, I could see that the text typed most recently ( ie, since the problem started) had a character that looked like an open square or box at the start of most lines. I deleted these and can't see any other extraneous symbols in AlphaX. However, I still get syntax errors when trying to paste code that was originally typed in using the built-in editor. If I retype the same thing in the same file using AlphaX, one line below the original, then copy and paste into the R console, it executes without generating syntax errors. So, it looks like something odd is going on with the built-in editor?

Re: [R] Cocoa GUI: pasting in R Console yields syntax error
Anthony I faced the same problem and it took me some time to spot the origin: I have no clue where it can come from!( I suspect this happened when I moved from 1.9.0 to 2.0.0, OS X 1.3...). I know that the built in R editor is very handy: what I do is a more myfile.r on the terminal to check if there are weird characters and then delete then directly with the R editor. Not very efficient I reckon: OS X gurus may have another solution!

Re: [R] Cocoa GUI: pasting in R Console yields syntax error
Thanks David. I'm glad I'm not the only one. I was beginning to wonder if I had really lost it.

Not very efficient I reckon: OS X gurus may have another solution!

[R] Rcmdr - doItAndPrint - summary method of S4-class object not in Rcmdr window but R Console
Dear list member,
John Fox proposed to me posting this problem to R-Help:
I have written a function suited for Rcmdr and included this in a R-file
located in Rcmdr/etc as well as an augmented `Rcmdr-menus.txt'.
Now, I am faced with the following problem:
method show() of a S4-class object works flawlessly, that is `doItAndPrint'
works flawlessly and its output is returned correctly into the Rcmdr-Window.
However, by using method summary() for the same S4-class object fails, in
the sense that the output is *not* printed in the Rcmdr window, but into the
R Console. The summary()-method contains cat() and slots of the S4-class
objects only.
My question is: How can it be achieved that method summary() of S4 objects
is printed in the RCmdr window and why, in the first instance, does it fail
to do so by using `doItAndPrint'.
Any help or pointer is much appreciated,
Best Regards
Bernhard

Re: [R] Rcmdr - doItAndPrint - summary method of S4-class object not in Rcmdr window but R Console
The FAQ Q8.1 does recommend that summary() methods do not print themselves
but returned a classed object to be printed.
What doItAndPrint does is to capture the result of an explicit print, so
it will only work for summary methods that follow that recommendation.
I do think doItAndPrint should be capturing all the output from a function
via sink(), and not just the print of the final result.

RE: [R] console under Mandrake
Thank you for your both answers, As you might have guessed, I am initiating myself in the Linux wizardry. I have absolutely nothing against command line, I was just heavily used to the Windows console mode; a terminal window is just fine. Actually, I only used the console to install packages from CRAN, anyway; I'm sure I'll find the commands for this. I read the manuals; it probably didn't work for me because I do not use GNOME but KDE. So command line it is... and most probably ESS.

But why you do not use any text ditor for writing functions and

I'm not sure if and how it works on Windows, but on Unix one of the
better kept secrets of the readline library is that you can embed
newlines by typing ctr-V ctr-J, e.g.
x - matrix(c(1,2,3,
4,5,6,
7,8,9), 3)
The nice thing is that it allows you to recall the entire command and
edit it (I don't think it survives being saved to the history file
though). If you have ever had to correct a typo in an expression that
has been split over 8 lines, you'll know what I mean:
up,up,up,up,up,up,up,up,RET,
up,up,up,up,up,up,up,up,RET,

Re: [R] writing several command line in R console
You can start the first line with (. Then everything you write will
NOT be syntactically complelte until you issue the closing ). I
learned this from Venables and Ripley, Modern Applied Statistics with S.
The + sign in front of each line is NOT something you should enter: R
changes its prompt to tell you that the previous line was not
syntactically complete.
I prefer to keep my code someplace else and then transfer a complete
function into R at one time. See
http://socserv.socsci.mcmaster.ca/jfox/Books/Companion/ESS/index.html;
Does this answer your questions?
Best Wishes,

RE: [R] writing several command line in R console
The R prompt should be though of as a one line editor or rather one
expression editor. You can not step between lines etc while editing an
expression. The + in front of each row placed there by R indicating
that even if you have typed ENTER the expression is not finished and
that R expect you to close it (normally by closing brackets, parentesis
etc). The + is just an indicator and will not be included in your
expression.
What you really want to do when you create functions etc is to write the
up in an external text editor, save them with the extension *.R, e.g.
twosam.R, and the use source to read the function in to R, i.e.
source(twosam.R)
Make sure to save your twosam.R file as *text*. If you're using Windows
you can use Notepad to do this. Also, you have to save the file in the
working directory of R. You can find the current working directory of R
by
getwd()
Alternatively, you'll have to specify the full path to the file when
using source
source(C:/My Documents/hb/twosam.R)
Hope this helps!

I would like to know how to step to the next line in the R
console editor
without breaking the continuity of my code
more clearly : if for example I write a function, so far i
have to write the
all code inside on the same line wich may become obscure as
the function is
more and more complex.
I would like to do like in the example of the manuels:
twosam - function(y1, y2) {
n1 - length(y1); n2 - length(y2)
yb1 - mean(y1); yb2 - mean(y2)s1 - var(y1);
s2 - var(y2)
s - ((n1-1)*s1 + (n2-1)*s2)/(n1+n2-2)
tst - (yb1 - yb2)/sqrt(s2*(1/n1 + 1/n2))tst }
all I can do is something like that:
twosam - function(y1, y2) {n1 - length(y1); n2 - length(y2)
+yb1 - mean(y1); yb2 - mean(y2)s1 - var(y1);
s2 - var(y2)
+s - ((n1-1)*s1 + (n2-1)*s2)/(n1+n2-2)
+ tst - (yb1 - yb2)/sqrt(s2*(1/n1 + 1/n2))tst }
with the sign + in front of each line
What does this sign mean? and how could I solve my problems Thanks

RE: [R] writing several command line in R console
Thanks to all
1) OK for the + sign and the problem of syntactelly unbreaking when you
open a { or a (
2) Thanks for the advise to use another editor for the functions. And then
the source() function. I tried it succesfully
Long life to R!

The R prompt should be though of as a one line editor or rather one
expression editor. You can not step between lines etc while editing an
expression. The + in front of each row placed there by R indicating
that even if you have typed ENTER the expression is not finished and
that R expect you to close it (normally by closing brackets, parentesis
etc). The + is just an indicator and will not be included in your
expression.
What you really want to do when you create functions etc is to write the
up in an external text editor, save them with the extension *.R, e.g.
twosam.R, and the use source to read the function in to R, i.e.
source(twosam.R)
Make sure to save your twosam.R file as *text*. If you're using Windows
you can use Notepad to do this. Also, you have to save the file in the
working directory of R. You can find the current working directory of R
by
getwd()
Alternatively, you'll have to specify the full path to the file when
using source
source(C:/My Documents/hb/twosam.R)
Hope this helps!
