Ошибка в if (inline) {: аргумент не интерпретируется как логический

Это связано с другим постом, который у меня есть, о добавлении новой строки fluidRow (conainting plot + selectInput) в мое приложение shinyDashboard.

Когда я запускаю приведенный ниже код, я получаю следующее

Error in if (inline) { : argument is not interpretable as logical

Я пытался повозиться с тем, как написан код, например удалите запятые, но мне не удалось найти способ избавиться от ошибки. Более того, я думаю, что это одна из причин невозможности создать дополнительный поток жидкости.

У меня есть ощущение, что это как-то связано с моими элементами управления вводом, но я не знаю, что именно!

Любая помощь будет оценена.
