У меня есть data.frame, который я могу построить с использованием matplot:
> dim(lhbyzone)
[1] 38070 21
> matplot(lhbyzone)
(no error occurs here)
Но если я возьму голову lh и попробую, это даст мне странную ошибку:
> foo <- head(lhbyzone,1000)
> matplot(foo)
Error in `rownames<-`(`*tmp*`, value = c("1", "2", "3", "4", "5", "6", :
length of 'dimnames' [1] not equal to array extent
Итак, возможно, что-то связано с именами?
> dimnames(foo)

Размеры выглядят одинаково? Это странно, так как matplot на исходной раме работает, но не на голове рамки. Что может быть здесь?
Редактируйте, хорошо, чтобы ответить на некоторые вопросы, и позвольте использовать thbyzone вместо lhbyzone, потому что он меньше и позволяет использовать голову вместо головы (.., 1000), чтобы уменьшить данные
