xyplot format axis
Hi All,
I'm trying to format the y-axis in an xyplot to show numbers with a comma
separating the thousands but I'm not able to do it using formatNum(y,
big.mark=","). This is what I have:
library(lattice)
year<-c(2003,2004,2005,2006,2007,2008,2003,2004,2005,2006,2007,2008)

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,

multilevel models and sample size
It is not a pure R question,but I hope some one can give me advices.
I want to use analysis my data with the multilevel model.The data has 2 levels---- the second level has 52 units and each second level unit has 19-23 units.I think the sample size is quite small,but just now I can't make the sample size much bigger.So I want to ask if I use the multilevel model to analysis the data set,will

can nlme do the complex multilevel model?
data from multilevel units,first sample the class ,and then the student in calss.following is the 2-level model. and the level-1 model deals with the student,and the level-2 model deals with the class level the students belong to.
Level-1 Model
Y = B0 + B1*(ZLEAD) + B2*(ZBUL) + B3*(ZSHY) + R
Level-2 Model
B0 = G00 + U0
B1 = G10 + G11*(ZWARMT) + U1
B2 = G20 + G21*(ZWARMT) + G22*(ZABLET) +

bivariate normal cdf
-- R Help List --
I am looking for a bivariate normal cdf routine in R. I have some fortran routines for this, which appear to be based on 15-point quadrature. Any guidance/suggestions on making these in loadable R-functions would be appreciated.
Thanks,
Dan

question about technieque do with large computation
The green book tells:"The basic technique is classic :keep it simple ."A long ,complicated expression or function is less fravorable than" a relatively small computations that combines calls to a few other functions to perform its tasks."
But I don't get the point totally.Can anyone give me an example to make me understand this rules totally?

what does this syntax mean?
i study the code of function ave,but i can understand one line of the syntax.
> ave
function (x, ..., FUN = mean)
{
n <- length(list(...))
if (n) {
g <- interaction(...)
split(x, g) <- lapply(split(x, g), FUN)
}
else x[] <- FUN(x)
x
}
my question is : what does "split(x, g) <- lapply(split(x, g), FUN)" mean?
thank you!

does multinomial logistic model from multinom (nnet) has logLik?
I want to get the logLik to calculate McFadden.R2 ,ML.R2 and
Cragg.Uhler.R2, but the value from multinom does not have logLik.So my
quetion is : is logLik meaningful to multinomial logistic model from
multinom?If it does, how can I get it?
Thank you!
ps: I konw VGAM has function to get the multinomial logistic model
with logLik, but I prefer use the function from "official" R

Dynamic reference, right-hand side of function
Hi!
Thanks for the replies!
I understand people more accustomed to R doesn't like looping much, and that thinking about loops is something I do since I worked with Stata a lot. The syntax from Peter Dalgaard was really clever, and I learned a lot from it, even though it didn't solve my problem (I guess it wasn't very well explained). My problem was basically that I have a data matrix

Um, if you insist on doing it that way, at least use
assign(varname, as.vector(get(varname)))

basename/dirname produce incorrect results
The incorrect result incurs when the file path contains Chinese character.
It seems that dirname/basename action on unit of byte instead of char, so
the result in the following example is half of what is expected.
> g<-"d:\\$BG!2L4^M-CfJ8(B\\$BG!2L4^M-CfJ8(B.txt"
> dirname(g)
[1] "d:/$BG!2L4^(B"
> basename(g)

how to word-wrap text in labels in plots?

Is there a way to get the long variable labels to automatically wrap so that all

:-)
I don't insist on anything, I'm just struggling to learn a new language and partly a new way of thinking, and I really appreciate the corrections. I hope I someday will be able to handle lists in R as easy as I handle loops in Stata...
Thanks again!

stacking vectors of unequal length
R-users --
I would like to make a single vector out of something like the following:
y0 <- rep(0,100)
y1 <- rep(1,20)
and stack them one on top of the other to a vector y with length 120.
Thanks,
Dan
