pooling categories in a contingency table
John Fox helped show me how to collapse the categories, pooling frequencies, in an n-way table, using levels()<- on an equivalent data frame: # create a table sex <- c("Male", "Female") age <- letters[1:6] education <- c("low", 'med', 'high') data <- expand.grid(sex=sex, age=age, education=education) counts

I have about 512 mb vram and 4 gb ram and intel core duo 2.4 ghz I have never experienced any problems with my graphics card untill i used it with wine on ubuntu. Suddenly I could not play the games I used to play in windows xp. I tested doom 95 and halo evolved and they both could not run and stuttered. I have no problems

regression constraints?
gday R gurus, I have a multivariate regression for which I want to constrain the coefficients to be > 0. Is this possible?

printing hclust with k clusters
howdy R friends, I've searched CRAN but to no avail... I'm trying to use mva's hclust and print out for say 10 clusters in batch. How do I do this?

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" >

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

merge aint merging
g'day R friends, can anyone please help me with a frustrating merge? The number of rows of a resulting merge is the smaller of the 2 dataframes used as input. What am I doing wrong?

queueing problems
howdy R friends, I'm new but I used to play with S+ a long time ago. Can someone please help me with how to approach this? I have some response time data I want to 'correlate' with other data. I believe queueing is involved so I need to prove somehow (F test?) that response ~ exponential(...) How do I go about this? I cant find exponential in 'nlm' or other functions.

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]

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"

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 >

Factor Analysis
Thanks to Brian Ripley for the time and effort put into developing the factanal package for R. I have found it very useful. However, in trying to replicate some results from previous research, I have run into the need for a couple of extensions and was wondering if they might find their way into future implementations. 1. Though maximum likelihood estimates might be more rigorous and

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". I was hoping to grab the best t

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? My TERM seems ok for other unix apps. I'm running under hpux 10.20 with R1.0.0 thanks, John Strumila -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-

howdy R friends, Can anyone help me with converting a ''unix'' date (seconds since 1970) into something readable?
