Ошибка в G * t(hat): неконформируемые массивы

Question

Пытаясь выполнить PERMANOVA, используя adonis в R. Добавленный в мою таблицу данных и факторы, тем не менее, я продолжаю получать ошибку выборки - Ошибка в G * t(hat): несоответствующие массивы

Нет данных N/A, и он работает с готовой матрицей данных и подмножеством моей собственной таблицы данных.

Пример данных, которые не работают;

subset<-matrix(c(0,0.000666667,0.001333333,0.000333333,0.000333333,0.019833333,0.007666667,0.014666667,0.0005,0.022833333,0.016833333,0.018166667,0.000666667,0.009666667,0.008833333,0.009166667,0.001333333,0.018666667,0.0295,0.031833333),ncol=4)

test_groups<-c(1,1,2,2)
adonis(subset~test_groups)

Ошибка в G * t(hat): неконформируемые массивы

Тестовые данные, которые действительно работают;

test<-matrix(data=c(0.1,0.1,0.3,0.1,0.2,0.3,0.1,0,0.3,0.1,0.2,0.3,0.1,0.2,0.3,0.1),ncol=4)

Почему это не работает?

Answer 1

Длина test_groups вектор равен 4, а число строк subset это 5.
Ниже я установил на 5 количество рядов subset и adonis Команда работает хорошо.

library(vegan) 
subset <- matrix(c(0,0.000666667,0.001333333,0.000333333,0.000333333,0.019833333,0.007666667,0.014666667,0.0005,0.022833333,0.016833333,0.018166667,0.000666667,0.009666667,0.008833333,0.009166667,0.001333333,0.018666667,0.0295,0.031833333),ncol=5)
test_groups <- c(1,1,2,2)     
adonis(subset~test_groups)

Вот результат.

'nperm' >= set of all permutations: complete enumeration.
Set of permutations < 'minperm'. Generating entire set.

Call:
adonis(formula = subset ~ test_groups) 

Permutation: free
Number of permutations: 23
