Interfacing C++ , MysQL and R
Hello!
After a presentation of some statistical analysis of process datas, (where the few R possibilities I was able to show made quite a big impression), I was asked if it was possible to program a statistical application which could be used directly by the end user.
Such an application would include a userfriendly interface (developped in C++), a db , a core statistical program, standard

multiple logistic regression
Dear R helpers!
Is there an utility for multiple logistic regression where the response is not ordinal? As the predictors do not satisfy the necessary hypothesis, I cannot use discriminant analysis.
Thanks and have a nice R-day

Hi!
I'm trying to do some ploytomous logistic regression using multinom() in the nnet package, but am a bit confused about interpretation of the results
Is it possible to get the following quantities:

still problems with predict!
Hi all,
I still have problems with the predict function by setting up the values on
which I want to predict
ie:
original df: p1 (193 obs) variates y x1 x2
rm(list=ls())
x1<-rnorm(193)
x2<-runif(193,-5,5)
y<-rnorm(193)+x1+x2
p1<-as.data.frame(cbind(y,x1,x2))
p1
y x1 x2
1 -0.6056448 -0.1113607 -0.5859728
2 -4.2841793 -1.0432688 -3.3116807

table lookup n R
Hello R helpers!
I looked but did not find a table-lookup R-utility. I could use a loop to do the job (old FORTRAN/C habits die hard) but if I have a big table in which I have to search for the values corresponding to a vector, I end up logically with a double loop.
Is there already such a utility? Otherwise, is there a way without loops?
Thanks as always

ordering levels
Hello!
I would like to know if there is a simple way to reorder levels of a given factor.Let's say that the vector
testf<-factor(c("red","red","red","blue","blue","white"))
levels(testf) : blue red white
should have reordered levels such as
levels(testf) : red blue white
(this is for presentation purposes)

color scale to label a plot
Hello R-helpers
I want to put a color scale in a plot:
I've got an xy plot where the values of the response (z=f(x,y)) is symbolically given by colors (like heat or rainbow color scale)
I would like to put such a scale with apprpriates labels in the plot, so as to facilitate the interpretation (like in a finite elements result plot)
How is taht possible?
Thanks

removing NA as a level
Dear R-helpers,
I have a problem which I suppose is trivila, but...
I have included NA values as factors ( (to be able to make nice printed summaries with NAs % ba category ) with the following code
dat$x.f<-factor(dat$x, exclude=NULL); levels(dat$x.f)<-c("A1","A2","A3","A4","NA"); length(dat$x.f)
Now, I want to impute the missing values.

using the name of an argument in a function
Hi all,
In a function, I need to get the name of a variable that has been used to
call the function.
For example, I want:
--- 8< ------
toto <- 3
fun <- function(y){
nameOfY <-deparse(substitute(y))
cat("name is ",nameOfY)
}
fun(toto)
# [1] name is toto
--- 8< ----
But deparse(substitute(y)) does not work all the time, especially when we
use generic function.

plotting results from leaps library
Hi
In trying to fit a linear model , I use the leaps() function to determine wich predictors I should include in my model.
I would like to plot the Mallow's Cp criteria against p with the indexes of selected model variates as points labels
Is there already such a function? (I could not find it)
