How to get standard deviation of rows in a matrix
Hi all, I am trying to find sd of my rows in a matrix and i get column sd inspite of extracting rows. I tried to do the sqrt(var(x)) but that did'nt work as well, Here is my data genes 15 24 63 40 25 42 46 35 23 53 37 45 30 37 50 55 40 51 30 48 x<-sd(genes[1:5,]) y<-sqrt(var(genes[1:5,])) I get 4 sds for the 4 columns instead of 5 sds for my 5 rows. Thanks you in advance.

comparing a vactor of values in IF statement.
Hi, my vector V<- c(1,0.5,0.06,0.056,0.01,0.04,0.4,0.9,0.82,0.1) if( V > 0.5) { V <- 1 - V } I get a warning saying only the first element will be used in comparing (if V > 0.5). However, my results tell me vis-versa ,it actually compares every element of the vector V with 0.5 and that is waht i want it to do. Using a for loop is expensive and time consuming since my actual

Help in Overlaying of 2 Plots on the same Device.
I'm trying to overlay a density plot on a previously plotted histogram. However, i need to use the same axis as of the 1st(histogram) plot to plot the second. My second plot is creating its own axis and causing my plot to extend the entire histogram instead of getting a subplot on a portion of the histogram. I tried 'fig' and 'new' parameters with no luck. Thanks in advance.

Least square minimization (non-linear)
Hi all, I think the last time i posted this topic i started on the wrong foot. Thnaks alot to everyone who responded. i'm coding in R(first time) for a paper my colleague is publishing. i plotted a histogram for 6000 values. I am told to plot experimental vs theoretical vlaues from the histogram and do a non linear least square curve minimization and compute the mean and sd of the new x

Non linear Square fit Function
Hi all, I'm trying to use the nls function to do a nls curve fit. I have a histogram for my data. I need to get athe best curve fit for this. i am plotting experimental vs the theoretical values. my experimental values are got from my dnorm function, mean=mean of my mid values(hist) and sd=sd of my mid values. For the theoretical i'm using mean and sd of all 20000 raw values as the start

Help in Customising NLS function to spit out Mean and SD of the new fit!!!
Hi all, I'm trying to customize the nls function code to spit out the sd and mean of the new fit. All it gives me are the fitted values. THis function seems to work fine for my project otherwise. All i need is the SD and MEAN. Can someone help me to customise. I frankly did not understand the nls code at all. I have 10 x and 10 y values from a histogram. I need to use nls to do the best fit

How to obtain nls parameter estimates
How can I receive parameter estimates for a given curve that has been fit with the NLS function. The problem is that I have a "n parameter" curve and I want the optimal fit. The NLS procedure gives me final function values and not the individual parameter estimates that were used to define this "best" fit. What function can I use to get these parameters? Thanks

Help in customising the NLS function to spit out mean and SD of new fit!!
i'm coding in R(first time) for a paper my colleague is publishing. i plotted a histogram for 6000 values. Taking the mean and sd of the midpoints i did a dnorm and got the densities. pl<-dnorm(trimmedvals,mean=midsmean,sd=midsSD) (now in a loop of 5 times) i plotted these experimental values against theoretical values using the nls function the following way.

Bug in VGAM z value and coefficient ?
Dear, When i multiply the y of a regression by 10, I would expect that the coefficient would be multiply by 10 and the z value to stay constant. Here some reproducible code to support the case. *Ex 1* library(mvtnorm) library(VGAM) set.seed(1) x=rmvnorm(1000,sigma=matrix(c(1,0.75,0.75,1),2,2))

an anti-overflow wrapper
The following code is a first attempt at a simple but flexible suid wrapper which checks argv[] and environment. It might introduce new security holes or have other bugs; using 1 as a general failure exit value may be the wrong thing to do. The wrapper reads a configuration file named /etc/wrapper.cfg; see the comments in wrapper.c for the file''s format. Flame, comment, or use at will.

[squid-users] debian Jessie squid with auth (kerberos/ntlm/basic) ERROR type NTLM type 3
Hai Amos, Thank you for your very clear responce.. few small questions.. Is there a way to setup the proxy for the following. 1) use negotiate kerberos for auth, ( which is working already for all domain joined machines ) 2) use a fall back that works, for now basic ldap works for non windows machines, and domain joined machines. 3) use any other fallback way for authentication users on windows

Help in customising the NLS function to spit out mean and SD ofnew fit!!
Doesn't look like nonparametric fit to me, since nls() is used to fit to a gaussian density, so the result is a gaussian density (with estimated parameter). What I do not understand is why people would do this. This is not the first time I've seen people doing this, on both R-help and S-news (if my memory is still any good). If the objective is to fit a Gaussian distribution to the

Winbind - how to map ADS group to Unix group
I am running 3.0.10-1.4E on RHEL4. The machine is a ADS member server. I would like to statically map the ADS group "Domain Admins" to the built in "wheel" group so all members of "Domain Admins" are in the "wheel" group. I have looked at the username map option, but I don't want a group of users mapped to a UID (this would defeat what I am trying to
