[R] problem in R-code

[thanoon younis]

Dear R-Users

After correct some errors in the code below i have only this error

"Error in if (BZ[i] < 0.25) { : missing value where TRUE/FALSE needed"

how can i solve this problem please?



N<-200;P<-9                       #Sample size
BZ=matrix(NA, nrow=N, ncol=1)


W=matrix(NA, nrow=N, ncol=1)


for (t in 1:100) {
  #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[i] < 0.25){
        W[i] = 1
      }else if(BZ[i] >=0.25 & BZ[i] < 0.5){
        W[i] = 2
      }else if(BZ[i] >=0.5 & BZ[i] < 0.75){
        W[i] = 3
      }else{
        W[i] = 4
      }}}}
