how to make list() return a list of *named* elements
If I combine elements into a list
b <- c(22.4, 12.2, 10.9, 8.5, 9.2)
my.c <- sample.int(round(2*mean(b)), 5)
my.list <- list(b, my.c)
the names of the elements seems to get lost in the process:
> str(my.list)
List of 2
$ : num [1:5] 22.4 12.2 10.9 8.5 9.2
$ : int [1:5] 11 8 6 9 20
If I explicitly name the elements at list-creation, I get what I want:
my.list <- list(b=b,

ploting a comparison of two scores, including the labels in the plot
Hello r-help!
I have data with two kind of ratings on status of 100 occupations. The
first kind of rating is on the percieved "objective" status that these
occupations have in society at large, and the second kind or rating is
on the status that the respondents think that these occuption *should*
have.
The ratings were originally integer values in the rage 1-9, but in the
current data,

simple usage of "for"
Hi list
I have a data frame I would like to loop over. To begin with I would
like crosstabulations using the first variabel in the data frame,
which is called "meriter".

which is the fastest way to make data.frame out of a three-dimensional array?
foo <- rnorm(30*34*12)
dim(foo) <- c(30, 34, 12)
I want to make a data.frame out of this three-dimensional array. Each dimension will be a variabel (column) in the data.frame.
I know how this can be done in a very slow way using for loops, like this:
x <- rep(seq(from = 1, to = 30), 34)
y <- as.vector(sapply(1:34, function(x) {rep(x, 30)}))
month <- as.vector(sapply(1:12,

getting random integers
I want 100 integers. Each integer, x, can be in the range 1 =< x => 10.
Does the following code give 1 and 10 the same chances to be selected as
2:8?
round(runif(100, min = 1, max = 10))

frequency table for multiple variables
Hi r-help!
Consider the following data-frame:
var1 var2 var3
1 3 1 4
2 2 2 3
3 2 2 3
4 4 4 NA
5 4 3 5
6 2 2 3
7 3 4 3
How can I get R to convert this into the following?
Value 1 2 3 4 5
var1 0 3 2 2 0
var2 1 3 1 2 0
var3 0 0 4 1 1
TIA,

read.spss, locale and encodings
I must be missing something obvious here:
According to the help page for read.spss, the reencode option is only
active when R is run under a UTF-8 locale.
read.spss can only import the SPSS file when run under a iso88591(5)
locale, under a UTF-8 locale I get:
Error in read.spss("wo.sav") : error reading system-file header
In addition: Warning message:

Student
Hi,
I have problem. In the function below (test and test2) i want the function
test not to print the variable data but i want the function test2 to use the
variable test$data.
This is the creation of the variable data:
> matrice=c(1:10)
> matrice=matrix(matrice,nrow=5,ncol=2)
This is the function test:
> test=function(data){
+ return(list(x=5,data=data))

Plot using colors
Dear R users,
I have a problem since I try to plot my datas with different colors.
plot(tvar, var, xlab="zeit [s]",ylab="Variation [%]", col = ifelse(var <=
varstability, 'green','red'))
this works well!
But since I add a type="l" to my plot, it will color all the plot with
green!!!
Is there any solution? I avoid to use teachingDemos.
Thanks.

function input as variable name (deparse/quote/paste) ??
Hi all
Say I have a function:
myname=function(dat,x=5,y=6){
res<<-x+y-dat
}
for various input such as
myname(dat1)
myname(dat2)
myname(dat3)
myname(dat4)
myname(dat5)
how should I modify the 'res' line, to have new informative variable name
correspondingly, such as
dat1.res
dat2.res
dat3.res
dat4.res
dat5.res
stored in the workspace.
This is only an example of a complex

speed up merge
Hello,
I have a nasty loop that I have to do 11877 times. The only thing that
slows it down really is this merge:
xx1 = merge(dt,ua_rd,by.x=1,by.y= 'rt_date',all.x=T)
Any ideas on how to speed it up? The output can't change materially (it
works), but I'd like it to go faster. I'm looking at getting around the
loop (not shown), but I'm trying to speed up the merge first.

Text wrap
Hi everyone.
I have a long label that I would like to split. I found that I could use
"strwrap" for simple text. However, this is not working with this label:
str = expression(paste("< 20 ?m phytoplankton ","(cells ? ",mL^-1,")"))
plot(...., ylab = strwrap(str,20),...)
I suspect this is because I'm using "expression" for form my label.

abbreviate or wrap dimname labels
For a variety of displays (mosaicplots, barplots, ...)
one often wants to either abbreviate or wrap long labels,
particularly when these are made up of several words.
In general, it would be nice to have a function,
abbreviate.or.wrap <-
function(x, maxlength=10, maxlines=2, split=" ") {
}
that would take a character vector or a list of vectors, x,
and try to abbreviate or wrap

Wrap names.arg text in barplot
Hello!
Does anyone know of a handy way to wrap the names.arg text in a barplot?
I'm creating a bar plot with rather long labels; I can adjust the margins,
but I'd also like to have the text wrap to about 4cm. Thanks!

How do I wrap a long mixed text/math expression in an axis label?
I would like to wrap a y-axis label onto two lines. My label is an expression
containing both text and math symbols. I have looked at plotmath,
strsplit(), strwrap(), deparse(), do.call(), substitute() and bquote().
Based on previous posts, I can get plain text to wrap. However, when I try
these methods on my label, the exact string is returned, rather than
evaluating the math symbols.

Converting a whole dataframe (including attributes) from latin1 to UTF-8
Hi list!
Short version: How do I convert a whole data.frame from latin1
encoding to utf8?
I get SPSS files with latin1 encoding. My OS is GNU/Linux and the
locale sv_SE.utf8, and I normally interface R with Emacs/ESS. I have
used the following hack to convert a data.frame in latin1 to utf8:

How to wrap or split labels on plot
Dear R gurus,
I want to wrap labels that are too long for a plot. I have looked at
strsplit(), substr(), nchar(), and strwrap(). I think it's some
combination but I'm having difficulty trying to figure out the right
combo. I think I need to create some new matrix containing the labels
already split, though I'm not sure if maybe there is a quick and dirty
way to address this

allowing line wrap for long strip text in xyplot (lattice)
Hi. Am brand new to R and to mailing lists - have never posted anywhere
before, so hope I do this right.
Am using R 2.9.1 with lattice graphics (just installed, fully up to date).
Am doing trellis xyplot with y (emp=employment), x (yearmo=a time measure)
and conditioning variable (indf - factor describing industry) -- i.e., (emp
~ yearmo | indf), where all three variables are in a dataframe. The
