store matrix in an arrary
Dear All
I want to store matrix in an array
Suppose s<-array(0,4)
for(i in 1:4)
s[i] <- read_matrix(a,2,2)
But the error - number of items to replace is not a multiple of replacement
length.
Can you suggest me any alternative method for storing a matrix in an array.
Thanks In advance.
Kind Regards

chunk row to new table/file
I have big .csv file. I would like to filter that file into a new table.
For example, I have .csv file as below:
f1 f2 f3 f4 f5 f6 f7 f9 f10 f11
t1 1 0 1 0 1 0 0 0 0 1
t2 1 0 0 0 0 1 1 1 1 1
t3 0 0 0 0 0 0 0 0 0 0
t4 1 0 0 0 1 0 0 0 0 0

Append tables
R Help:
I have read a number of tables into R with identical headings and I
would now like to make a single table that has all the data appended
under this single heading line.
for example:
t1 <- read.csv("f1",header=TRUE)
t2 <- read.csv("f2",header=TRUE)
all <- c(t1,t2)
#all is now twice as wide as t1 or t2 with the same number of row!!!!
#I need to know how

Change of parsing parameters to functions between 0.63.1 and 0.63.3 ?
Hi,
I wonder whether the mechanism of parsing parameters to functions has
changed between 0.63.1 and 0.63.3? The following code yeils different
results in R 0.63.1 (Version 0.63.1 (Dec 5, 1998)) and R 0.63.3.
cave<-function(x,a,b)
{
return(c(mean(x[a],na.rm=T),mean(x[b],na.rm=T)))
}
datx <- data.frame(rbind(c(1,2,3,4),c(4,5,6,7)))

Aggregate weights for a unique set of rows
Hi, all together. I have - a maybe trivial - problem with aggregating a
list of weights.
Here is the problem:
- At first I have set of nodes (X/Y-coordinates) and associated weights,
where the set
of nodes is typically not unique
- I want to get a set of unique nodes and the sum of associated weights
I am grateful for any help
See for example:
# weights:
w <- c(1, 1, 1, 1, 1)

error: expected memory with 32-bit signed offset
Hi,
I want to encode Loongson ISA initially

It is equivalent to:

lb $2,0($1)
I just use mem_simmptr as the default value of DAGOperand MO ,
because MipsMemAsmOperand use parseMemOperand to parse general

Extract pairs (rowname, columname) from a matrix where value is 0
Dear sir,
I have a matrix like
a<-matrix(c(0,2,0,4,0,6,5,8,0),nrow=3)
colnames(a)<-c("F1","F2","F3")
rownames(a)<-c("A1","A2","A3")
a
F1 F2 F3
A1 0 4 5
A2 2 0 8
A3 0 6 0
I want to extract all pairs (rownames, columnames) from which the value in
the matrix is 0
The result should be something like this

GridR
Dear All
I am doing one distributed data mining program. So I selected GridR
package for the distributed programming.
*grid.init(service="local",debug=FALSE, localTmpDir="GridRTmp/")
grid.apply("x",UCS, wait=TRUE )*
UCS is a function.
When I execute this statement, I have some errors like :

Conditionally adding a constant
I am trying to add a constant to the previous value of a variable based on
certain conditions. Maybe there is a simple way to do this that I am missing
completely. I have given an example below:
df <- data.frame(x = c(1,2,3,4,5), y = c(10,20,30,NA,NA))
> df
x y
1 1 10
2 2 20
3 3 30
4 4 NA
5 5 NA
I want to add 2 to the previous value of y, if x exceeds 3 (also will have
to handle NAs in

Using factor variables with overlapping categories
ear folks ?
I have a question, though it is more of a logic- or a good
practices-question than a programming question per se. I am working with
data from the American Community Survey summary file. It is mainly
categorical count data. Currently I am working with about 40 tables covering
about 35 variables, mainly in two-way tables, with some 3-way and a handful
of four-way tables. I am going to

How to select the scale parameter for Gabor transform (Rwave)?
Dear list,
I am trying to choose the scale parameter for the cgt transform but I don't
know how to do it. In time I would like to be able to separate points 30
samples apart, and in frequency I would like to separate bands 0.04 Hz
apart. I tried the two approaches described below and they gave me
different results. I would appreciate advise on how to do this.

R/S-Plus equivalent to Genstat "predict": predictions over "averages" of covariates
Hi all
I'm doing some things with a colleague comparing different
sorts of models. My colleague has fitted a number of glms in
Genstat (which I have never used), while the glm I have
been using is only available for R.
He has a spreadsheet of fitted means from each of his models
obtained from using the Genstat "predict" function. For
example, suppose we fit the model of the type

a fast table() for the 1D case
Hi,
table1D() below can be up to 60x faster than base::table() for the 1D
case. Here are the detailed speedups compared to base::table().

(or more if 'useNA="always"')
o With factor/integer/numeric/character of length 1M and 9 levels
