Dear R community Hope all of you are fine. I have a question regarding the an error message. Actually, I am trying to generate classification trees using tree package.

[R] loop problem
Dear R members
I have a problem regarding storing the lists.
Let
L=number of distinct values of any predictor (say L=5)
P=number of predictors (say P=20)
g1 - c()
for(i in 1:P){
if(L 1){
for(j in 1:(L-1)){
g -
g1[j] - g
}
}
g2[]=sort.list(g1)
}
Now the question is: What should we use inside brackets of g2[], whether
i or some thing else? If L is not greater than 1 then there will be a NULL
for g2. We don't want to store it in g2, so how can we handle this problem.
Looking forward for some help. Thanks and
best regards

Dear friends
Hope you all are fine. Suppose we have a list of arrays.
a1=c(4,4,4,4,0,4,4,4,0,3,3,0,0,0,0,0); a1=array(a1,dim=c(4,4));
a2=c(4,4,4,
4,0,4,4,4,0,3,3,0,0,0,0,0); a2=array(a2,dim=c(4,4));
a3=c(4,4,4,4,0,3,3,4,0,4,4,0,0,0,0,0); a3=array(a3,dim=c(4,4));
a4=c(4,4,4,4,
4,0,3,3,3,3,0,4,4,4,0,0,0,0,0,0); a4=array(a4,dim=c(5,4));
a5=c(4,4,4,4,4,0,4,
4,4,4,0,3,3,3,0,0,1,1,0,0); a5=array(a5,dim=c(5,4));
a6=c(4,4,4,4,4,0,1,1,1,1,
0,4,4,4,0,0,3,3,0,0); a6=array(a6,dim=c(5,4));

if ( nrow(l[[x]]) != nrow(y) | ncol(l[[x]]) != ncol(y) ) FALSE

Using the above function, we are able to get frequency of each most

similar components of the list. For example, [[1]] and [[2]] are most
repeated
similar out of all. But if we consider the combinations at each row of
each

[[6]] and

[R] Request: How to draw a tree
Dear friends As a result I get an array containing certain no of rows and columns. In the resultant array first row represents first node of a tree starting from left side, second row represents second node of that tree and so on. In the example below, the resultant tree contains 6 nodes. We get the first node on L.H.S by splitting top node using variable 10, node 2 by taking start from the R.H.S node then splitting it using variables 7 and 11 respectively [ Note: 0's are not the variables ]. All the nodes are connected on this way to get the whole tree. We can easily draw it manually. Now the question is, is it possible to draw it using R. Any help in this regard is needed.

Re: [R] request: most repeated component of a list
Thanks for the effort but still we are far from the desired result. May be this
example will help you to understand the situation. Example
a1=c(1:12); a1=array(a1,dim=c(3,4)); a2=c(1:12); a2=array(a2,dim=c(3,4));
a3=c(1:16)
a3=array(a3,dim=c(4,4));
a=list(a1,a2,a3);
a
[[1]]
[,1] [,2] [,3] [,4]
[1,]147 10
[2,]258 11
[3,]369 12
[[2]]
[,1] [,2] [,3] [,4]
[1,]147 10
[2,]258 11
[3,]369 12
[[3]]
[,1] [,2] [,3] [,4]
[1,]159 13
[2,]26 10 14
[3,]37 11 15
[4,]48 12 16
Here [[1]] and [[2]] are same out of three (internal values wise). The whole
array [[1]] or [[2]] is in majority. So i want to get the whole array or
component of list which is in majority. The result should be like this
[,1] [,2] [,3] [,4]
[1,]147 10
[2,]258 11
[3,]369 12
Hope it is much more clear as before.

That is indeed different from what I thought the first time.
x - sapply(1:length(l), function(x) {
sum(sapply(l, function(y) {

names(x) - names(l)
Then, x has the same names as l, and x[i] is the number of matches that
l[[i]] has...so you want the index or indices of max(x).

try the following:

do.call(paste, c(as.data.frame(x), sep = \r, collapse = ))
}
pats - sapply(a, ff)
ind - which.max(table(pats))

I hope it helps.

Thanks for the effort but still we are far from the desired result. May be
this example will help you to understand the situation. Example
a1=c(1:12); a1=array(a1,dim=c(3,4)); a2=c(1:12);
a2=array(a2,dim=c(3,4)); a3=c(1:16)
a3=array(a3,dim=c(4,4));
a=list(a1,a2,a3);
a
[[1]]
[,1] [,2] [,3] [,4]
[1,]147 10
[2,]258 11
[3,]369 12
[[2]]
[,1] [,2] [,3] [,4]
[1,]147 10
[2,]258 11
[3,]369 12
[[3]]
[,1] [,2] [,3] [,4]
[1,]159 13
[2,]26 10 14
[3,]37 11 15
[4,]48 12 16
Here [[1]] and [[2]] are same out of three (internal values wise). The
whole array [[1]] or [[2]] is in majority. So i want to get the whole
array or component of list which is in majority. The result should be like
this
[,1] [,2] [,3] [,4]
[1,]147 10
[2,]258 11
[3,]369 12
Hope it is much more clear as before.

That is indeed different from what I thought the first time.
x - sapply(1:length(l), function(x) {
sum(sapply(l, function(y) {
if ( nrow(l[[x]]) != nrow(y) | ncol(l[[x]]) != ncol(y) ) FALSE
else sum(y != l[[x]]) == 0
}))
} )
names(x) - names(l)
Then, x has the same names as l, and x[i] is the number of matches that
l[[i]] has...so you want the index or indices of max(x).

x=array(x,dim=c(3,6,7))
apply(x,3,function(.mat){
rows - table(apply(.mat,1,function(z){
# remove the zeros
z - z[z != 0]
paste(z,collapse=' ')
}))
# remove empty strings
rows - rows[names(rows) != ]
if (!is.null(rows)){
return(names(rows)[which.max(rows)])# return(table(names(rows)))
} else return(NULL)
})
I am trying to get frequencies of all the sequences instead of most repeated
using return(table(names(rows))). But i could not get the desired results (i
mean frequencies of all possible sequences)e.g. for first sector the result
should be
1
3
and so on. Please suggest me some suitable way. Thanks

Re: [R] request: most repeated sequnce
Dear R community
Initially i thought my problem has been solved but one thing which i found e.g.
if
1. All the elements of a sector are zero e.g
, , 7
[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10]
[1,]000000000 0
[2,]000000000 0
[3,]000000000 0
[4,]000000000 0
[5,]000000000 0
2. Majority of the rows consist of zeros e.g.
, , 5
[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10]
[1,]440000000 0
[2,]440000000 0
[3,]000000000 0
[4,]000000000 0
[5,]000000000 0
Actually
zeros are not my values. I get values and fill the remaining parts with
zeros like x=array(0,dim=c(3,6,5)). Now according to first strategy
000000000 0 are most repeated
sequence of rows in both of above cases. But i don't want to consider
cases where all elements are zeros and interested to get 44
0000000 0 or just 4 4 in case 2.

[R] request: To access a particular list
Dear R community
I have a problem to access particular list. I have a code given below where
there is recursive process. It is not possible to run it because there are few
other functions involved inside like sv, LN, RN etc.
k=0; n=0; variable=c(); vr-list()
func - function(data,testdata)
{
.
.
if(..){
n-n+1; vr[[n]] - variable; print(vr)
}else
{
k - k + 1; data1 = data; data2 = testdata;
s=sv(data1)[[1]]; s1=s[1]; s2=s[2]; variable[k] - s1
data=LN(data1,s1,s2); testdata=LN(data2,s1,s2)
func(data,testdata);
data=RN(data1,s1,s2); testdata=RN(data2,s1,s2)
func(data,testdata)
}
}
func(m,w)
Actually i made an global array to store s1 named variable. It contains k
values. When it enters into if, i made a list of variable named vr. So it
will make n lists. If i get the print out of vr, i will get
[[1]]
[1] 4

But if i print(vr[[n]]), i get result like an array
[1] 4
[1] 4 4 3
[1] 4 4 3

I want to access a particular list vr[[n-1]], but it gives an error

I tried a lot to solve the following problem but could not. I have two arrays

Now i want to rbind the results of r1 and r2 for each time. Now the order of
r3[ j, ] will become 2 by 150. I used the following form in the loop
r3[ i,]=rbind(r1[ i, ], r2[ i, ])
But there is an error message

I want to know that integer e.g. in the first column 1 is in majority. Similarly in the third column 4 is in majority. So what is the suitable way to get the desired integer for each column. I am looking for some kind reply. Thanks example: x=matrix(c(1,1,1,2,2,2,2,3,3,3,3,4,4,4,4,4,1,2,3,3),ncol=4) x [,1] [,2] [,3] [,4] [1,]1234 [2,]1241 [3,]1342 [4,]2343 [5,]2343 best regards Muhammad Azam Ph.D. Student Department of Medical Statistics, Informatics and Health Economics University of Innsbruck, Austria [[alternative HTML version deleted]] __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
