Hi, I have a matrix [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] [1,]131131123 2 [2,]131211122 1 [3,]122321112 1 [4,]321113121

[R] "non-numeric argument to binary operator"

Hello, For reasons unclear to me I am getting above error message when I change the value of b in the following code: rm(list=ls()) library("Hmisc") set.seed(4) #seems to have an effect on t(apply b=10 pop.props = c(0.6,0.2,0.2) x=matrix(pop.props,nrow=nn,ncol=length(pop.

Re: [R] "non-numeric argument to binary operator"

"Most likely reason is that the number of unique values in the rows of habs is not the same." Yes, I think that is the problem, thank you. How would I write the code to include 0s in the matrix, ie, I want to have a record of when 1, 2, or 3 does not get sampled, to come up with a frequency of e
