many curves to the same plot
Dear all,
I would like to plot under the same plot
many curves like
mycdf<-ecdf(runif(100))
plot(mycdf)
curve(mycdf,from=-1,to=1)
mycdf<-ecdf(runif(200)+3)
plot(mycdf)
curve(mycdf,from=-1,to=1)
as you can see each new call to curve redraws (erases) the window. How I can have an effect like
plot(mycdf)
lines(mycdf2)
lines(mycdf3)
I would like to thank you in advance for your help

error message fitting tcopula
Hi r-users,
I really need help in fitting the t-copula. I try to reproduce the example given by Jun Yan in “Enjoy the joy of copula” but I’m not sure how to correct the error based on the error message. I tried so many ways but still could not get it working.
loglik.marg <- function(b, x) sum(dgamma(x, shape = b[1], scale = b[2], log = TRUE))
ctrl <- list(fnscale = -1)

Hi r-users,
I try to fit the t copula using the gamma marginals. But I got error message which I don't really understand.
Thank you for any help given.

Copula fitMdvc:
Hello,
I am trying to do a fit a loglikelihood function with Multivariate
distribution via copulas with fitMdvc. The problem is that it
doesn't recognize that my beta is a vector of km parameter and when I try
to run it it say that the length of my initial values is not the same as
the parameter.
Can somebody guide me where my mistake is.
Thanks,
Elisa.

Using copulas with user-defined marginal functions
I am trying to make a loglikelihood function using copulas. I am trying to
use mvdc to find the density function. When I run this I got the error that
the pdf and cdf of my function tobit doesn't exist. Can somebody guide me
where my mistake is?
dtobit <- function(beta,sigma, x, y) {ifelse(y>0, dnorm(y,x%*%beta,
sigma),(1-pnorm((x%*%beta)/sigma)))}

problems with copula
Hi, I'd like to know why using the program "R" I can't add a number of

Meta-analysis with zero values for mean and sd
Hi!
I want to do a meta-analysis with count data for treatement/control cases.
Mi problem is that I need to use zero values (an informative value) for the
mean and standard deviation for one of the treatement, but R has a
problem: "Studies
with zero values for sd.e or sd.c get no weight in meta-analysis". I can
agroup the case by Family (byvar=Family).
¿anybody help me? Thanks!

Distribuciones de probabilidad
Hola Comunidad,
Tenia al siguiente duda
¿hay alguna forma de que R me de la Esperanza y Varianza de una distribución según sus parámetros?
es decir, si tengo una weibull de parámetros "X" y "Y" para la esperanza hay una formula, pero me gustaría saber si hay una función en R que le diga algo como
Esperanza(weibull, shape = "X", scale = "Y") y ya devuelva

smb.conf
I added a hosts deny line to above and denied one specific ip address.
I then deleted that line but added hosts allow and made this equal to any
ip address within previous "denied ip address's subnet. However, the
afore-mentioned ip was still denied and I had to allow it individually.
Can anyone tell me why.
Thanks

Sampling two exponentials
Hi all,
I am going to sample two variables from two exponential distributions, but I want to specify a covariance structure between these two variables. Is there any way to do it in R? Or is there a "Multivariate Exponential" thing corresponding to the multivariate normal? Thanks in advance.

RMySQL typing Problem (bigint unsigned)
Dear Group,
if anyone has experience with the RMySQL Package maybe this behaviour is know:
Reading data from a table into R the fields with datatype bigint(20) unsigned are transformed in some way: e.g. the query "select * from orders where userid = 14929859848712890325" selects the correct case but in R the userid is changed to 14929859848712890368. What happened here? This

Generating bivariate or multivariate data with known parameter values
Greetings,
I'm interested in generating data from various bivariate or
mulitivariate distributions (e.g. gamma, t, etc), where I can specify
the parameter values, including the correlations among the variables. I
haven't been able to dig anything up on the faq, but I probably missed
something. A nudge in the right direction would be appreciated.
