correlatation matrix
Hi there,
I wonder if there is a way of efficiently generating a correlation matrix of two expression matrices. I want to correlate miRNA and mRNA expression and used the following code:
##dat.mi miRNA expression matrix, dat.m mRNA expression matrix
nc <- nrow(dat.mi)
cor.mat <- data.frame(rep(NA,nrow(dat.m)))
pval.mat <- data.frame(rep(NA,nrow(dat.m)))
for(i in...

question about ar1 time series
...1 (or alpha in another text-books ;-)) < 1 (in fact 0 < rho1 < 1) so that
#the system can be stationary.
#Where var_serie is the variance of the serie
cat("\n Hello, this is creat_AR1_synt_ser.R. \n These are the input
parameters: synt_series(ar1_length, rho1, ...), where rho1 is the
correlat. coef.\n")
ar1 <- function(x, rho1, af)
{
return(x*rho1 + runif(1, -af, af))
}
#Spin-up for the AR1 series. For this case is enough with this amount
spinup <- function(x0, rho1, af)
{
xt <- x0
for (i in 1:100) {
xtp1 <- ar1(xt, rho1, af)
xt <- xtp1
}...

Reality check: IPFW sees SSH traffic that sshd does not?
This note is essentially a request for a reality check.
I use IPFW & natd on the box that provides the interface between my home
networks and the Internet; the connection is (static) residential DSL.
I configured IPFW to accept & log all SSH "setup" requests, and use natd
to forward such requests to an internal machine that only accepts public
key authentication; that
