Dear All,
I am trying to create an artificial binary matrix such that each cell has a
probability of 0.048 of having a 1. So far the closest I've come is us by
using a random poisson distribution with a mean of 0.048, but I can't figure
out how to limit the max value to 1. Otherwise that would
Hi,
I am currently trying to execute the following command:
f<-factanal(factors=k$Components$nparallel,covmat=m,n.obs=2287,rotation="varimax",control=list(opt=list(method=c("BFGS"
but keep getting the error: L-BFGS-B needs finite values of 'fn'
I can't figure out what I am doing wrong here,
Dear All,
I am trying to fill in a blank vector ("a") with one value at a time, with
the value of the number of rows in a randomized dataset with rowSums=0.
Below is the code I've got so far, but what I want to be as the last line is
" a[1st NA,]=nz"
such that this will run until all of my NAs a
My question would be related more to time-dependent ROC (survivalROC package):
I would like to know how true positives (TP) and false positives (FP) are
related to the order of survival times and diagnostic markers. That is, having
the a set of TP and FP, each of them is calculated from which di

Erik and Steve,
Thanks again for your help, both solutions do exactly what I need.

That would be a z test, not a t test, wouldn't it? And it would only
be meaningful if the distribution of the estimator is approximately
normal, which we

The exact syntax will depend on the class of your 'column of data'. If
it is a dataframe, for example, then try
matrix(yourData[,1], 3, 3)

Hi french,
Here is a suggestion:
x <- c(2, 3, 4, 2, 1, 6, 6, 4, 7)
matrix(x, ncol = 3)
# [,1] [,2] [,3]
# [1,]226
# [2,]314
# [3,]467
with x the column of data you have.
HTH,

Hi,
I have a dataset called 'fish'. fish$Species returns extract 1. When I use
fish$Species != c("CRA","PHC"), i.e. I want all species except "CRA" and
"PHC", I get extract 2 which is blatantly wrong. Can anyone see what I'm
doing wrong?

Hello,
I cannot figure out how to set the column widths (either relative or absolute)
for the heatmap function - the full manual hints that layout and lcm will
control this, but I haven't had any luck.
This is in R 2.9.2 compiled for either FC10 or SUSE11.1 (x86_64)... and am
sending the out

(1) Is there a (simple) way of getting cloud() to do *both*
type="p" and type="h"? I.e. of getting it to plot the points
as points *and* drop a perpendicular line to the underlying plane?
(2) Is there a way of telling cloud() to drop its lines to the
floor of the bounding box, rather than to t
Hi Jim,
Take a look at ?"%in%", especially its first example.
