R function not writing matrix with col indexing












0















I am trying to map values from a stochastic process. While in the past the following code produced a correct matrix with number_draws rows, it is not not working and giving me the following error:



Error in X[, i] <- Marginals_Beta_Var[U[, i], i] : 
incorrect number of subscripts on matrix


as well as turning X into a huge matrix with 10000x10000 dimension. Code:



number_draws = 10000
X = matrix(nrow = number_draws, ncol = 18)

for (i in 1:18){
X[,i] = Marginals_Beta_Var[U[, i], i]

}


The Matrix U has indices for columns for mapping to other marginals



> head(U)
[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10] [,11] [,12] [,13] [,14] [,15] [,16]
[1,] 30 2 164 486 30 362 317 81 431 197 408 139 106 500 398 199
[2,] 275 40 217 173 172 366 218 205 96 255 184 255 38 328 375 175
[3,] 169 117 407 112 343 38 88 406 266 77 69 483 40 303 136 236
[4,] 245 261 54 364 287 224 320 246 446 71 340 7 250 360 341 75
[5,] 332 356 197 194 248 268 108 133 429 409 121 472 418 473 289 121
[6,] 328 60 160 310 181 411 183 499 339 350 354 28 104 278 444 210
[,17] [,18]
[1,] 98 197
[2,] 469 205
[3,] 117 23
[4,] 39 457
[5,] 362 359
[6,] 329 304


Marginals_Beta_Var has 500 rows and 18 columns, each with a different value.



The code has previously worked. I am calling this within a function, perhaps I messed up the global values.



Thank you for your help.

  • I'm assuming the type in "number_draws" (says "numbe_draws" instead) in your example here doesn't occur in your actual code?

  • Yes, you are right. The Marginals_Beta_Var[U[, i], i] is apparantly a tibble, could that be the problem?
