Dear R - Users I have a small problem when i generated two column with 200 rows and as follows Q1[i,1]=sample(4, 200, replace = TRUE); Q1[i,2]=rbinom(200,1,0.7) the first vector is ordered categorical variable and the second vector is dichotomous variable but when i run this code i found this error Error in Q1[i, 2] = rbinom(200, 1, 0.7) : number of items to replace is not a multiple of replacement length Any help would be appreciated. Regards
