288 Entry to this mode runs the hooks in ess-mode-hook.
290 You can send text to the inferior ESS process from other buffers containing
292 `ess-eval-region' sends the current region to the ESS process.
293 `ess-eval-buffer' sends the current buffer to the ESS process.
294 `ess-eval-function' sends the current function to the ESS process.
295 `ess-eval-line' sends the current line to the ESS process.
296 `ess-beginning-of-function' and `ess-end-of-function' move the point to
297 the beginning and end of the current ESS function.
298 `ess-switch-to-ESS' switches the current buffer to the ESS process buffer.
299 `ess-switch-to-end-of-ESS' switches the current buffer to the ESS process
300 buffer and puts point at the end of it.
302 `ess-eval-region-and-go', `ess-eval-buffer-and-go',
303 `ess-eval-function-and-go', and `ess-eval-line-and-go' switch to the S
304 process buffer after sending their text.
306 `ess-load-file' sources a file of commands to the ESS process.
308 \\[ess-indent-command] indents for ESS code.
309 \\[backward-delete-char-untabify] converts tabs to spaces as it moves back.
310 Comments are indented in a similar way to Emacs-lisp mode:
311 `###' beginning of line
312 `##' the same level of indentation as the code
313 `#' the same column on the right, or to the right of such a
314 column if that is not possible.(default value 40).
315 \\[indent-for-comment] command automatically inserts such a
316 `#' in the right place, or aligns such a comment if it is
318 \\[ess-indent-exp] command indents each line of the ESS grouping following point.
320 Variables controlling indentation style:
321 `ess-tab-always-indent'
322 Non-nil means TAB in ESS mode should always reindent the current line,
323 regardless of where in the line point is when the TAB command is used.
325 Non-nil means automatically newline before and after braces inserted in S
328 Indentation of ESS statements within surrounding block.
329 The surrounding block's indentation is the indentation of the line on
330 which the open-brace appears.
331 `ess-continued-statement-offset'
332 Extra indentation given to a substatement, such as the then-clause of an
333 if or body of a while.
334 `ess-continued-brace-offset'
335 Extra indentation given to a brace that starts a substatement.
336 This is in addition to ess-continued-statement-offset.
338 Extra indentation for line if it starts with an open brace.
339 `ess-arg-function-offset'
340 Extra indent for internal substatements of function `foo' that called
341 in `arg=foo(...)' form.
342 If not number, the statements are indented at open-parenthesis following
344 `ess-expression-offset'
345 Extra indent for internal substatements of `expression' that specified
346 in `obj <- expression(...)' form.
347 If not number, the statements are indented at open-parenthesis following
349 `ess-brace-imaginary-offset'
350 An open brace following other text is treated as if it were
351 this far to the right of the start of its line.
353 Extra indentation for line if it starts with `else'.
354 `ess-close-brace-offset'
355 Extra indentation for closing braces.
357 Non-nil means distinguish between #, ##, and ### for indentation.
359 Furthermore, \\[ess-set-style] command enables you to set up predefined ess-mode
360 indentation style. At present, predefined style are `BSD', `GNU', `K&R', `C++',
361 `CLB' (quoted from C language style)."
