このリストに特定の ascii 文字を書きたいと思います (このリストは ascii と呼ばれます)。たとえば、「\032」と表示されている場所にスペース「 」が必要です。ascii[1:32] <- "\032"...しかし、これは正確に「\032」をそれらの位置に書き込みます...「\045」などのいくつかの文字で動作します.. .

ascii[1:32] <- " " とは言わないでください。リストに他の ASCII 文字を紹介したいのですが、文字よりも数字を書いたほうがいいので...

どうもありがとう！

編集：更新

R は数字のみを使用します。たとえば

myascii<-c(65,66,67)

rawToChar(as.raw(myascii))

ABCを与える

したがって、配列を変更するときに「\ 066」の代わりに66を使用するだけです
