Dear R-users
I have a problem in the code below, the problem is because i want to change
the variable BZ which is a vector with 200x1 dimension to the var. W which
is categorical variable with same dimension of BZ but with categorical
values with 4 categories but i got on only zero values in w why? any help
would be appreciated.
N<-200;P<-9 #Sample size
BZ=numeric(N)
W<-numeric(N)
for (t in 1:1) {
#Generate the data for the simulation study
for (i in 1:N) {
#transform theta to ordered categorical variables
for(j in 1:1){
if(BZ[j] < 0.25){
W[j] = 1
}else if(BZ[j] >=0.25 & BZ[j] < 0.5){
W[j] = 2
}else if(BZ[j] >=0.5 & BZ[j] < 0.75){
W[j] = 3
}else{
W[j] = 4
}}
#Input data set
data<-list(N=200,P=9,Q=W)
}} #end
W
Regards

Why don't you just multiply by four, round, and add one? B.

I have not mustered the stamina to go through your code in detail, but it looks to me like the "1:1" constructions are typos and should perhaps be "1:N". Aside from that, I conjecture that what you want to accomplish could be very simply done with the cut() function. This is not entirely clear since it is not really clear what you want to accomplish. Note that you appear to evince a misunderstanding of R data structures; a vector of length 200 is subtly different from a 200 x 1 array. I think you should study up on some basic R (e.g. read "An Introduction to R") before proceeding further. cheers, Rolf Turner -- Technical Editor ANZJS Department of Statistics University of Auckland Phone: +64-9-373-7599 ext. 88276 On 04/11/15 16:02, thanoon younis wrote:> Dear R-users > > I have a problem in the code below, the problem is because i want to change > the variable BZ which is a vector with 200x1 dimension to the var.

Sorry, not round. floor() B.

Thank you for your response
I have a vector of unknown values BZ which is defined already BZ=numeric(N)
and i want to transfer BZ to ordered categorical variable with 4
categories W but when i write this code
for(j in 1:1){
if(BZ[j] < 0.25){
W[j] = 1
}else if(BZ[j] >=0.25 & BZ[j] < 0.5){
W[j] = 2
}else if(BZ[j] >=0.5 & BZ[j] < 0.75){
W[j] = 3
}else{
W[j] = 4
}}
i found the values of W are only 0, but if i change for(j in 1:N) the
values of W will be only 1. how can i solve this problem?
Regards
