Dear Experts,
The following is my Iterator. When I try to write a new function with
itel, I got error.
This is what I have:
supDist-function(x,y) return(max(abs(x-y)))
myIterator - function(xinit,f,data=NULL,eps=1e-6,itmax=5,verbose=FALSE) {

Dear all,
I have a list of correlation coefficient matrixes. Each matrix represents one
date.
For example
A[[1]]

A 1 0.2 0.3
B 0.2 1 0.4
C 0.3 0.4 1
Thanks this works. Only, I need to reference in the formula using indexes.

I guess what you want is:
- change the line :
xnew-f(xold,data)
into
xnew-f(xold,data, itel)
- change your mat function to take itel as an extra parameter:
mat-function (x, data=NULL, itel) {return (1+x^itel)}
That should do the trick (though I haven't checked whether the
Hi casperyc,
While Jim Holtman's solution is quite neat, I thought I would add a
multiple histogram to the discussion in case that was what you wanted:
library(plotrix)
barp(t(x.m[,2:5]),names.arg=x.m[,1],col=rainbow(4))
legend(20,2500,paste(V,2:5,sep=),fill=rainbow(4))
Jim
one way is the following:
A - replicate(10, cor(matrix(rnorm(30), 10, 3)), simplify = FALSE)
triA - sapply(A, function (m) m[upper.tri(m)])
rowMeans(triA, na.rm = TRUE)
I hope it helps.
Best,
Dimitris

I am facing an error when I try to plot envelopes of a fitted model in
spatstat. My model is fitted using the Geyer Saturation process as follows:
* geyer.fit-ppm(points, ~el+asp, Geyer(r=1, sat=2), covariates=list(el=el,
asp=asp))*
It fits well, but when I try to plot the envelopes to

Hello again!
Sorry, if it's a simple question - I am very bad in working with strings.
I have a vector of strings:
x-c(2000.1,2000.2,2000.10,2000.12)
I'd like to change it so that it the month always has 2 digits, like this:
2000.01,2000.02,2000.10,2000.12
Is it possible?
Thanks a lot!

Suppose your data frame is named df. Try this:
data.frame(df[,1],1,df[,2:5])

The error message doesn't say that the file doesn't exist --
it says that it contains a symbol which can't be resolved,
in this case dgemv_ . A quick google search shows that this

installed the BLAS library in some

but forgot to up the preallocation part, I should have used a variable there
instead so that only one place needed to be changed.

Usually the easiest way to solve problems like this
is to put all the dataframes in a list, and then use
the Reduce() function to merge them all together at the
end. You don't give many details about how the data frames
are constructed, so it's hard to be specific about the
best way
Here are 2 possibilities:
cbind( iris[,1, drop=FALSE], 1, iris[,2:5] )
cbind( iris, 1) [ ,c(1,6,2:5) ]

Hi Kate,
is.na() does not work on entire data frames. You just need to specify
the column, for example:
data[is.na(data[, 8]), 8] - 0
if the NAs were in column 8.
Best regards,
Josh

Thanks a lot, Phil.
I decided to do it via the list - as you suggested, but had to do some
gymnastics, which Reduce will greatly help me to avoid now!

Could anyone give me some clues as to the best way to debug this error message?
I think it is from the passing of variables back to R from the jags function
which does Bayesian fitting. The curious part for me is that the error
messages seem random, yet the input data are always the same.
You could use the Reduce function to get the sum of the matrices, then if
there are no missing vales just divide by the number of matrices. If there are
missing values then you would probably need to use Reduce again to count the
number of non-missing values.
Since all the matrices are the
Kate -
As the error message indicates, num.strata is a
factor. This can occur when you're reading in data
and R encounters a non-numeric value which was not
specified in the na.strings= argument to read.table.
To do what you want, you'll need to convert it to a
character variable first:
Try this:
as.data.frame(append(iris, 1, after = 2))

whoops, I did not mean that. is.na() has a data frame method, but
there are assignment issues (as you saw) when you use it that way.
