tapply, sorting and the heap
howdy gurus, I'm new and green and I was hoping for a tiny bit of your expertise. I'm running out of virtual memory (heap?) when summing using tapply. I've already used --vsize=90M on my hpux machine. (details below) Can I pre-sort or something to prevent my error? thanks, John Strumila john.strumila at corpmail.telstra.com.au > gc()["Vcells","total"] [1]

recommendations on use of -> operator
I have never used -> but I noticed at http://github.com/jiho/r-utils/blob/master/beamer_colors.R that some people do. In fact, the above-named code has a sort of elegance about it (except for the use of "=" for assignment...). To my eye, -> calls to mind a type of assignment that is meant to stand out. For example, perhaps it would make sense to use -> to assign

R on Macintosh OSX Tiger
Hi. I'm not having any luck installing the binary for the new Macintosh OS called "Tiger". I get error messages as below. Can anyone offer me some advice? (PS: I checked the bug list first but a search on "Tiger" turned up nothing so I hope it's OK to post here.) Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared

question on axis box with asp=1
I've been using (and loving) R for quite a while now, but I have to admit that something simple is still stumping me. The question is how I can control the box within which a plot is drawn, in cases where I'm controlling the aspect ratio with the "asp" argument. The problem comes up in pdf() and png() output formats, but also with interactive windows, and so I'll

How to do linear regression with errors in x and y?
QUESTION: how should I do a linear regression in which there are errors in x as well as y? SUPPLEMENT: I've seen folks approach this problem by computing eigenvectors of the covariance matrix, and that makes sense to me. But I'm wondering if this has a "pedigree" (i.e. if it makes sense to folks on this list, and if it's something that has been published, so I can refer to

R 1.7.1 is released
I've rolled up R-1.7.1.tgz a short while ago. This is a patch version mainly fixing up an assortment of issues (see below). Note also that it comes with an updated set of recommended packages, fixing a couple of nasty issues in at least foreign and nlme. You can get it from http://cran.us.r-project.org/src/base/R-1.7.1.tgz or wait for it to be mirrored at a CRAN site nearer to you. Binaries

R on os390
G'day R friends, I didn't get any replies on the main list so I thought I'd try with the experts. I was wondering if anyone's ported R to os390. If so, are the vsize and nsize limits the same as other platforms? I could really annoy those SAS guys then. thanks, John Strumila john.strumila@team.telstra.com

cant find "get"?
howdy gurus, I was wondering if someone could help me with what looks like a simple problem. I found this great function called "get" which allows me to work out my object name at run time. Unfortunately it's not letting me assign values with it. What am I doing wrong? thanks, John Strumila > names(get(file.name))[1] [1] "X14.59.23" >

lm variable name limit?
gday R gurus, has anyone seen this lm problem? When I add 2 bytes to the variable name (via names), lm returns an error. It's as if there's a limit to the size of the variable names. Any suggestions? thanks, John Strumila > names(y)[12:14] [1] "Log.SQLServer.Locks.RID.Lock.Wait" "Log.SQLServer.Lock" [3] "xxaa"

Export a plot/figure to excel or word?
Hi all, I have created forest plots using the package "meta" that I submitted as pdf for publication. I just received an email from the editor asking me if I could send these files in an Excel or MS Word format such that they can treat them as tables with box plots. I am not sure if I can do this... Is this possible? I've tried the capture.output command, but I get a blank MS Word

ghostscript errors
gday R friends, Since I had random errors with ghostscript 6.01 I thought I'd upgrade. After upgrading to gs6.5 I've had problems. Originally, gs failed complaining about lack of "__sysconf" in glibc2.2 so I upgraded glibc. Now I get this. Note that it used to work with gs6.01. I realise this is probably a ghostscript problem but you never know... thanks, John Strumila >

somebody's stolen my probabilities
gday gurus, could someone please help me with this one? Can't find it in the doco. summary of my lm object gives "Pr(>|t|)" but coef doesn't. How do I get hold of these probabilities within an object? There doesn't seem to be an appropriate attribute within the object - I was hoping for something like "my.lm$probabilies".

command history under cursor keys
g'day R friends, I was hoping someone could provide me with advice as to my dysfunctional 'arrow' keys. Instead of browsing thru my command history they just move my cursor. What have I done wrong?

internet2 and proxies
gday R gurus, I've never attempted to use download.file before on my win2k machine but this version 1.4 looks exciting. However, I'm not getting something right. I've passed my R shortcut --internet2 and I can tell it's using the wininet calls because it's asking about authentication but how do I tell it my username/password? The help file only talks about user/pw for non
