Hi, there,
I found density function cannot work well on UNIX.R
version 2.13.1 (2011-07-08), Platform: i386-pc-solaris2.10 (32-bit)
Here is an example from R doucments which can work well on other version.
plot(density(c(-20,rep(0,98),20)), xlim = c(-4,4))#
But right now the estimated probab
SAS can merge two data set A, B in different way, A or B, A and B, A not B,
Can R merge function do the same way?
Thanks

Thanks for all you guys' help above.

Actually my question is for Multivariate Normal
Â
m1<-c(2.5,3.5,4.5)
m2<-c(-3,-4,-5)
m3<-c(100,120,130)
n1<-length(data$x)
sigma1<-matrix(c(1,0.3,0.4,0.3,1,0.2,0.4,0.2,1),nrow=3,byrow=T)
Â
trait1<-ifelse(data$x==1,list(rmvnorm(n1,mean=m11,sigma=sigma1)
I think I figure it out.
ifelse(data1$x==1,rnorm(12,2,1),ifelse(data1$x==2,rnorm(12,-2,1),rnorm(12,110,1)))
Please correct me if I am wrong. Thanks

Se
I need use different parameters of distribution for different case to
generate random value, but I use ifelse, the generated value is fixed
without change.
Here is example
data1
y x
1 1 2
2 2 1
3 3 2
4 4 3
5 5 3
6 6 1
7 7 2
8 8 1
9 9 1
10 10 3
11 11 3
12 12 2
ifelse(data1$x
Hope I can get quick help from here, I have a bunch of c, c++ included main
function and makefile. It works well on both UNIX and windows. I tried to build
R package which include this C++ program and several other R functions. R
function here are independent c++ code. I prefer to define one R
