Duncan, I would like an option for all comments and blanks to be echoed. The reason is that I am designing a mechanism for connecting ESS to Rgui using source(). It works for me now, but is not smooth enough to post until I do a little bit more work on it. Therefore I want an option for the R Console to display all the lines in my source() code. When the seven lines below are sourced, only lines 1,2,4,5,6 are echoed. Lines 3 and 7 are not echoed. This means that well-commented user source code will not have complete comments in the output transcript in the Console.
## comment 1 123 ## comment 4 456 ## comment 7 What I would also like, but I believe would be much harder for you to provide, is a way to get individual lines sent from ESS into the same place that lines that are manually typed go. The reason is that multi-line commands, such as 2+ 3 cannot currently be sent one line at a time (using ESS C-c C-n) to Rgui. They can be sent to any other R or S-Plus process one line at a time. I would like the same capability for the Rgui Console. The plan that I am developing now can send multiple lines over, either by highlighting them and using C-c C-r, or by surrounding them with blank lines and using C-c C-c.

Comments are already echoed, leading blank lines are not (but blanks in comments are). For example: > temp.ttt <- "ttt <- 1\n\n# comment\n\nttt" > cat(file="c:/temp/temp.R", temp.ttt) > source("c:/temp/temp.R", echo=TRUE) > ttt <- 1 > # comment > > ttt [1] 1 (I ran this in the patched version, but I believe the behaviour would be the same in the release as well.) I forget exactly why I chose to suppress leading blanks, but the workaround of commenting the first of them is so easy, I don't think it's worth the trouble to add an extra option.
