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.

Hello, Try th following. Q1 <- matrix(c(sample(4, 200, replace = TRUE), rbinom(200,1,0.7)), ncol = 2) Q1 Hope this helps, Rui Barradas Em 17-09-2015 15:37, thanoon younis escreveu:> 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 > >
