推荐答案

我假设上传"是指加载到 R ".有几种方法可以做到这一点，以下是两种.请注意，第一步是拥有完整路径的正确文件列表(或使用适当的wd)

I am assuming that by "upload" you mean "load into R". There are several ways to do this, below are two. Note that the first step is having the correct list of files with full path (or be working in the appropriate wd)

# Get the list of files
#----------------------------#
  folder <- "path/to/files"
  fileList <- dir(folder, recursive=TRUE)  # grep through these, if you are not loading them all

  # use platform appropriate separator
  files <- paste(folder, fileList, sep=.Platform$file.sep)


# Load them in
#----------------------------#
  # Method 1:
  invisible(sapply(files, source, local=TRUE))

  #-- OR --#

  # Method 2:
  sapply(files, function(f) eval(parse(text=f)))
