Matrix in R
Hi everyone, I'm building a matrix in R with a cycle for like this: pp_ris2=matrix(NA,6,6) for(i in 0:6){ for(j in 0:6){ if(i>j){ pp_ris2[i,j]=myfunction} else if(i==j){ print(c(i,j)) pp_ris2[i,j]=myfunction} }} but the result is: [,1] [,2] [,3] [,4] [,5] [,6] [1,] 0.062 NaN NaN NaN NaN NaN [2,] 0.083 0.022 NaN NaN NaN NaN [3,]
