[R] Infinite loop running Mod_R/Rapache
I installed mod_r according to the specifications, and have been trying
to get the demo script to work correctly. I am running debian, the
latest build of R, apache 2 with prefork mpm, and the latest mod_r. Is
anyone else using this module successfully? I added:
LoadModule R_module mod_R.so
Location /test/hello
SetHandler r-handler
Rsource /var/www/html/test.R
RreqHandler handler
/Location
to my http.conf and
test.R in /var/www/html is:
handler-function(r){
apache.write(r,h1Hello World!/h1)
OK
}
When I start apache2, my /tmp directory fills with rtmp directories
until memory is exausted. The first time it created 32,000 before I
noticed. Does anyone have any idea as to what I could be doing wrong, or
have a software configuration that works? Thank you for all of your
help. ~BJ

[R] plotting box plots on same x
I am trying to construct a graph of 6 box plots of blood pressures. I want them to be on a single set of axis and I want the SBP to be ontop of the DBP. I have an array bp with the data in it and I tried a[1,]-c(145,60,147,62,140,57) a[2,]-c(160,75,160,74,160,70) a[3,]-c(140,55,140,65,142,55) boxplot(data.frame(a), main = Blood Pressures, at=c(1,1,2,2,3,3), names=c(sit,,lie,,stand,)) which is close to what I want, but it gives me a bunch of empty space at the end. is there a better way to do this to avoid this? As always, Thank You. ~Erithid __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html

Re: [R] box plots without whiskers
Hmm ok, that seems to work with that example, but when I add an at= option i get graphs that are only verticle lines.

The output is a collection of verticle lines that are as long as the boxes should be. boxplot(data.frame(a),staplelty=0, whisklty=0, main = Boxplots, at=c(1,1,4,4,6,6,8,8), names=c(Base Line,,Sit,,Stand,,Lie,),ylab=DBP SBP) does though. So I thank you for your help. Didnt mean to get yellled at over what seemed like a decent question. The mailing list archives say you have to use the lattice package to achieve the effect I wanted.. Anyhow.

[R] I never made any assumption athat anyone had any obligation to do anything
I just asked a question. If I was too vague, then i am sorry. I dont expect anyone to help me, but I thought that it was ok to put the question out there in case someone wanted to help me. I didnt expect abject hostility for it. Human decency was the only thing I did expect. If my question was a pain,badly formatted, or too juvinile, then i have no problem being ignored.I asked a question that the archives did not satisfactorily answer. I appreciate the help of the poeple on this list as they are an invaluable resource, especially since the R documentation is sketchy at times. I am sorry for wasting everyones time. I just dont like being yelled at first thing in the morning for asking for help on a help list.

Basically, i want to create a boxplot from population data, with a solid line for the median, and then a dotted line for a specific persons value. Is there a way to artificially introduce another line or mark of some kind in a box plot? Thanks again for all of yoru help.

[R] formals or args question
Hello again, thank you again for all of your help. I am trying to get
the arguments for a function, in a way that I can handle them. If I do
args(fun), it doesnt really do what I want. If I use formals(fun) i get
output like:
$a
$r
$s
Now, lthis is supposedly a list, but if i say formals(a)[[1]], I get
nothing. I am just trying to get a vector with teh arguments of a
function so I can loop over them.
ex; a-function(p,r){p+r}
want: vector of c(p, r)
The documentation for args and formals is quite confusing. Thanks again!

You need the names of the elements of the list formals produces, not
their content!

[R] simple question, i hope
How do you output a list to a text file without the extra line numbers and stuff? I have a list b, and tried zz-textConnection(captest.txt,w) sink(zz) b sink() close(zz) but that isnt what i want, because i get [[1]] [1] a etc. Is there a simple way to do the R equivalent of this perl code? open(OUT,out.txt); print OUT @b; close OUT Thank you for your help.

Re: [R] pls -- crossval vs plsr(..., CV=TRUE)

There are two reasons: 1) The call plsr(y ~ X, 6, data = NIR, CV=TRUE, method=kernelpls) is incorrect. The `CV' argument of the superseded `pls.pcr' package has been replaced by the `validation' argument, so the correct call would be NIR.plsCV - plsr(y ~ X, 6, data = NIR, validation=CV, method=kernelpls) (If you had done R2(testing.plsNOCV), you would have gotten exactly the same as with the R2(NIR.plsCV) above.) 2) plsr(... , validation = CV) and crossval(...) both by default use CV with 10-fold _randomly selected_ segments, which means that each time you run the cross-validation, you will get slightly different results. (Try running R2(crossval(testing.plsNOCV)) a couple of times.) If you want the same segments in two separate calls, either add the argument segment.type = consecutive or interleaved, or specify the segments explicitly with the `segments' argument (see ?crossval or ?mvrCv for how). The segments actually used in a cross-validation is stored in the $validation$segments component of the object, i.e. testing.plsCV$validation$segments. (By the way, `method = kernelpls' is not needed, as it is the default fit method for plsr (and mvr).) -- Bjørn-Helge Mevik __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
