RpadUtil: Rpad utilities

In Rpad: Workbook-style, web-based interface to R

Description

Rpad utilities to generate filenames or URL's

Usage

  RpadEnv()
  RpadURL(filename = "")
  RpadBaseURL(filename = "")
  RpadBaseFile(filename = "")
  RpadIsLocal()

Arguments

filename

the name of a file.

Value

RpadEnv returns the (non-exported) environment “.RpadEnv”. Useful for peeking inside the environment for debugging purposes.

RpadURL returns the URL for the given filename: "./filename" for the local version of Rpad and "/Rpad/server/dd????????/filename" for the server version. Use this to output HTML links for the user.

RpadBaseURL returns the base URL: "filename" for the local version and "/Rpad/filename" for the client-server version. Use this to point the user to data files or other links on the server that is somewhere permanent. (The current R working directory is not permanent in the client-server version.)

RpadBaseFile returns the file name relative to the base R directory: "filename" for the local version and "../../filename" for the client-server version. Use this in R to read in data files or save data files somewhere permanent.
