推荐答案

你有没有看帮助(pdf)?

Did you look at help(pdf) ?

用法:

 pdf(file = ifelse(onefile, "Rplots.pdf", "Rplot%03d.pdf"),
     width, height, onefile, family, title, fonts, version,
     paper, encoding, bg, fg, pointsize, pagecentre, colormodel,
     useDingbats, useKerning)

参数:

file: a character string giving the name of the file. For use with
      'onefile=FALSE' give a C integer format such as
      '"Rplot%03d.pdf"' (the default in that case). (See
      'postscript' for further details.)

对于 1)，您将 onefile 保留为默认值 TRUE.多个图进入同一个文件.

For 1), you keep onefile at the default value of TRUE. Several plots go into the same file.

对于 2)，您将 onefile 设置为 FALSE 并选择具有 C 整数格式的文件名，R 将创建一组文件.

For 2), you set onefile to FALSE and choose a filename with the C integer format and R will create a set of files.
