[ESS-bugs] Starting evaluation... hangs (another try)

[Richard M. Heiberger]

ESS is not interpreting the R language.  The only way ESS knows it is required
to read a line is to look at the first character on the next line.  Consider
what happens when you start a long computation: the cursor sits at the beginning
of a line.  You don't want ESS to start reading new information at the point.
You want it to wait for your output to appear.  ESS sees what you are calling a
blank continuation prompt as an instruction to wait for output.

I recommend that you use the standard continuation prompt.

ESS is very smart about the prompts.  There are at least two ways to
get the effect that I think you are looking for.

1. When you have a multi-line command
in either the *R* buffer or in a myfile.rt buffer, you can place the cursor
on any line of the command and press the ENTER key.  The entire command, stripped
of the prompts, is sent to R for evaluation.  

2. When you are in a myfile.rt buffer,
you can use the two- or three-command sequence to turn the buffer into an R script.

## convert the entire buffer
C-x C-q     ## turn off read-only
M-x ess-transcript-clean-buffer

## convert the highlighted region
C-x C-q     ## turn off read-only
### highlight a region
M-x ess-transcript-clean-region


Now write the buffer to a new my.constructed.file.r file.
You will probably want to edit out the false starts and redundant commands
