Matlab code to R code
Dear r-users,
I would like to convert my Matlab code to R-code, however it dies not work as expected. Hope somebody can help me to match Matlab and r codes.
R code:
rr <- function(r,cxn)
{
tol <- 1E-4;
for(i in 1:n)
{
t1 <- (1+(i-1)*r)*log((1+(i-1)*r))
t2 <- (i-1)*(1-r)*log(1-r)
rri <- ((t1+t2)/i*log(i))-cxn
rr <- rri > tol
}
round(rr,4)
}
rr1 <- rr(0.5,0.0242) ; rr1
Matlab code:
function F = cxncnr(r)
n = 4;
% terms
t1 = (1+(n-1)*r)*log((1+(n-1)*r));
t2 =...

sapply code
Hi r-users,
I have this code here, but I just wonder how do I use 'sapply' to make it more efficient
lamda_cor <- eigen(winter_cor)$values
> lamda_cor
[1] 1.3459066 1.0368399 0.8958128 0.7214407
lamda_cxn <- function(dt)
{ n <- length(dt)
term <- vector(length=n, mode="numeric")
for (i in 1:n)
{ term[i] <- (dt[i]/n)*log(dt[i]/n) }
#sum(term)
cxn <- 1 + (1/log(n))*sum(term)
cxn
}
lamda_cxn(lamda_cor)
> lamda_cxn(lamda_cor)
[1] 0.01861457
Thank y...

Troubleshooting ZFS performance with SIL3124 cards
...al 2m58.863s
user 0m0.001s
sys 0m10.636s
gives me for this run a 8192/178 gives me around 46MBytes / second...
That is really sucky speed
for 12 drives. However this speed varies since the hangups seems to
occur on random and for a
random time.
If you look at the output from iostat -cxn 1 below you find that the
first one is okay but the
second on the disks are in 100 %w... and it stays at 100 %w for a few
seconds.

OpenSSH Compatiblity Problems.
Not sure which list this should go to, so I'll include both.
When I SSH from a 2.9.9p2 client to a OpenSSH 2.1.1 server, it often
hangs at this point.
It will hang there for days on end.
If I open up 9 xterms and run that command, 2-3 will login.
I have no problems using ssh1 (commercial).
And openssh has no problems logging into newer servers > 2.1.1.
Anyone know why this might be?
