Hi:
The idea is as follows:
* string your four matrices into vectors, cbinding them so that the
columns correspond to what you want as the (1,1), (1, 2), (2, 1) and (2, 2)
elements, respectively, of the matrix/table to be used for the Fisher test;
* Operate row-wise on the constructed matr
Hi,
I would recommend reformatting the data as a 2x2x1000 array and using apply.

Hello
I have 4 1000*1000 matrix A,B,C,D. I want to use the corresponding element of
the 4 matrices. Using the "for loop" as follow:
E<-o
for (i in 1:1000)
{for (j in 1:1000)
{
E<-fisher.test(matrix(c(A[i][j],B[i][j],C[i][j],D[i][j]),2))#call
fisher.test for every element
}
}
Why not just use matrix(runif(9),nrow=3) ?

Your example works because you have only 5 really long labels. I tried
changing 5 to 474 because that is how many I have and the plot looks
illegible. Should I increase the margin or the height of the plotting
window? Thanks for your help again.

Thanks for that - I just two seconds ago sent a reply to the list
complaining because you didn't provide one. However, the code below
doesn't work.

I should give an example

Gavin and Stefan,
Both the subset commands and the flag were exactly what I needed. On another
note, I'm dealing with variables that are categorical and have long names
like "Task XYZ", "Task ABC" "Task CCC"
When I try to plot against the probability it doesn't show me the Task name
anymore. How

The above doesn't make any sense and can't be working or doing what you
think it is doing.
Lets dissect this command:
yy <- poisson2[poisson2$Reboot.Id==
yy<-poisson2[poisson2$Reboot.Id=="Reboot
2",poisson2$Task.Status=="F",,drop=FALSE]
doesn't work either? Any other ideas?

How do you access all the column attributes associated with a column reboot
instance?
The variables
poisson2 ~ a matrix with 10,000 rows and 8 column attributes.
Things I tried:
This command only returns a vector for one of the column attributes
x1_prob <- poisson2$Probability[poisson2$Reboot.
I suspect you probably need to provide an example that illustrates why
this seems difficult:
> x <- 1:10
> f1 <- function(x) exp(x)
> g1 <- function (x) log(x)
> h1 <- function (x) x^(1/2)
# any of these functions would return a 10 element vector if given x
as an argument
> f1(x)*g1(x)*h1(x
Hi,
I'm a new R user and would appreciate your help regarding the following: Can
I create a matrix whose elements are n functions of a vector x? In my
problem I have 3 vectors (a,b,c) with elements a=[f1(x) f2(x)fn(x)];
b=[g1(x) g2(x)gn(x)]; c=[h1(x) h2(x)hn(x)]. I need to create a fin
