How to extract x rows to get x pvalues using t.test
Hi all,
My data
genes

[5,] 47 72 67 34
stu<-t.test(genes[,1:2],genes[,3:4])
> stu$p.value
[1] 0.4198002
i get 1 pvalue for the entire col1:col2 Vs col3:col4. I am trying to get 5 p values for the 5 rows i have.
I am trying to avoid a for loop coz my

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

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.

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.

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

question: access IR class Instruction from DAG SDValue
Seems llvm cannot pass metadata to MachineInstr, or setting operand description in class Instruction and pass to class MachineInstr.
Is it a good idea to extend llvm kernel structure to having this feature?

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
