Problem when creating matrix of values based on covariance matrix
...arrow compared
to the simulated data.
None of the eigenvalues of the observed covariance matrix are
negative, and it appears to be a positive definite matrix. Here is
what I did to create the simulated data:
Chol <- chol(CEUcovar)
Z <- matrix(rnorm(20351 * 8368), 8368)
X <- t(Chol) %*% Z
sample8 <- data.frame(as.matrix(t(X)))
> dim(sample8)
[1] 20351 8368
cov8=cov(sample8,method='spearman')
[earlier I've also tried sample8 <- rmvnorm(1000,
mean=rep(0,ncol(CEUcovar)), sigma=CEUcovar, method="eigen") with as
'bad' results, much larger covariance value...

dtmf Caller-id detection before first ring
Hi dears,
I am from saudi arabia and using asterisk 1.6.2.13,Dahdi-2.3.0 and
Digium, Inc. Wildcard AEX800 8-port analog card (PCI-Express) .
I am facing problem with detecting caller id before first ring.I
recorded the dahdi channel using dahdi_monitor command. Where I am
able to see and hear caller-id dtmf tones.
Pl tell me the procedure to upload recorded file if you needed.

Now I would like to define a function that will crop the p-values from an Anova (so that I can use the function with a 'for loop' later on to go through all the genes):
> p.fun <- function(arg) {
two_way_anova <- aov(arg ~ age * treatment, data = exam...
