clipr 0.3.0

• Introduces clipr_available which checks to see if the system clipboard is
  writeable/readable. This may be useful if you are developing a package that
  relies on clipr and need to ensure that it will skip tests on machines (e.g.
  CRAN, Travis) where the system clipboard may not be available. Thank you to
  @jennybc for this suggestion.
• Implements genuine testing of clipr functionality with thanks to some deft
  environment variable settings added by @jennybc.
• Two Rstudio addins: one to copy the value returned when a highlighted
  expression is evaluated, and another that copies the console output.

clipr 0.2.1

• Introduces read_clip_tbl, a convenience function that takes tab-delimited
  text from read_clip (such as that copied from a spreadsheet) and parses it
  with read.table. Thank you to Steve Simpson (@data-steve) for the original PR.
• write_clip(object_type = "table") has a new internal implementation (writing
  to a temporary file rather than using capture.output) which should
  dramatically shorten the time it takes to write very large tables to the
  clipboard. Thank you to @r2evans for this suggestion.

clipr 0.2.0

• Several changes to write_clip
  • The separator to be used when writing a character vector can now be
    explicitly declared using breaks. breaks=NULL will default to
    system-specific line breaks for both vectors and tables.
  • write_clip will default to formatting data.frames and matricies with
    write.table, allowing easy pasting of tabular objects into programs like
    Excel. Option object_type="auto" will check the object type to decide on the
    correct formatting, or the user may explicitly state object_type="table" or
    object_type="character".
    • clipr will default to sane system-specific options for write.table(),
      however you may pass any custom desired options via write_clip
    • return_new=TRUE (the default behavior) will return the formatted
      character string that was passed to the system clipboard, while
      write_clip(return_new=FALSE) will return the original object.
• Introduces clear_clip, a wrapper function for write_clip("") for easy
  clearing of the system clipboard.

clipr 0.1.1

• Bug fix that removes the explicit test for "Linux" in favor of a check for "xclip" or "xsel"
