Это хорошо работает при печати всей страницы без усечения; однако эти результаты бесполезны для последующих шагов, которые я должен предпринять. Эти результаты объединяют \r и \n, которые мне нужны для анализа текста. Например, я хотел бы извлечь имена официальных лиц на первой странице. Следующее работает нормально:
> library(stringr)
> officials <- str_sub(str_extract(txt[1], "(?<=\\b\r\nOfficials).+?.(\\b\r\n)"), start = 3L, end = -3L)
> officials
[1] "#15 Zach Zarba, #11 Derrick Collins, #12 CJ Washington"
Однако, если бы я был знаком только с результатами, полученными с помощью cat(txt[1]), я бы не знал, что нужно включать \r\n в "(?<=\\b\r\nOfficials).+?.(\\b\r\n)".
Как распечатать одну страницу целиком в исходном закодированном формате?
