Как отделить слова от текста и превратить каждое слово в элемент вектора?

У меня есть следующее предложение:

It is tricky for authors to figure out which keys will work, and how their values will be specified. Lamentably, it may be necessary to read the source code of an R package like rmarkdown to understand all of the details. However, usually, there is some relief in the fact that there is one example working document to exemplify the settings for a particular back end and authors can adjust and modify those values. The key:value pairs may may a difference at several stages in the compilation process.

Я пытался разместить весь текст в векторе.

То, что я сделал, это поместил все в вектор.

x<-c("It is tricky for authors to figure out which keys will work, and how their values will be specified. Lamentably, it may be necessary to read the source code of an R package like rmarkdown to understand all of the details. However, usually, there is some relief in the fact that there is one example working document to exemplify the settings for a particular back end and authors can adjust and modify those values. The key:value pairs may may a difference at several stages in the compilation process.")

Затем я использовал функцию strsplit для разделения каждого слова следующим образом:

palabras<-strsplit(x, "\\s")

Что я нахожу:

[1] "It"          "is"          "tricky"      "for"         "authors"     "to"          "figure"      "out"        
 [9] "which"       "keys"        "will"        "work,"       "and"         "how"         "their"       "values"     
[17] "will"        "be"          "specified."  "Lamentably," "it"          "may"         "be"          "necessary"  
[25] "to"          "read"        "the"         "source"      "code"        "of"          "an"          "R"          
[33] "package"     "like"        "rmarkdown"   "to"          "understand"  "all"         "of"          "the"        
[41] "details."    "However,"    "usually,"    "there"       "is"          "some"        "relief"      "in"         
[49] "the"         "fact"        "that"        "there"       "is"          "one"         "example"     "working"    
[57] "document"    "to"          "exemplify"   "the"         "settings"    "for"         "a"           "particular" 
[65] "back"        "end"         "and"         "authors"     "can"         "adjust"      "and"         "modify"     
[73] "those"       "values."     "The"         "key:value"   "pairs"       "may"         "may"         "a"          
[81] "difference"  "at"          "several"     "stages"      "in"          "the"         "compilation" "process."   

Но я не знаю, как преобразовать все эти слова в вектор.

То есть иметь вектор из 88 элементов.

Я не знаю, что еще делать ...

Есть ли функция, которая позволяет мне решить эту проблему простым способом?
