Re: [R] How to use multi paragraph comment like /* and */ in cpp?
Tks for all your help, finally i choose the way in Rstudio ctrl+shift+C, and
do twice to cancel those comments. It's enough for me now. BTW, I also like the
way:
if(FALSE) {} :)

Re: [R] How to use multi paragraph comment like /* and */ in cpp?
One way I know to do this is (in bash) to use a dummy variable and make the
comment a multiline character string:
dummy <- c("
This is my multiline
comment or code block.
")
or if printing does not disturb you, just use:
"
...
"
Use ' if you have " in the block.
Other workarounds are here, which you find when using a search engine:

Hope this helps.
@Duncan: sorry sending the mail to you twice.

Re: [R] How to use multi paragraph comment like /* and */ in cpp?
In R-studio, you can also select whatever you want to comment out, and
press CTRL-SHIFT-C to comment the selection in one go.
To uncomment it all in one go again, you can select it again and press
CTRL-SHIFT-C again.

What I do in cases like that is wrap the code in a FALSE statement so it won't
get executed: its easy to add and remove as needed.
If (FALSE) {
...Code to exclude
}

Even though I can easily mark such a block and use the general
emacs comment keyM-;
to comment each of those lines,
I often prefer
if(FALSE) {
...
...
...
}
which in the case of a single function definition which is only
one R expression can even do without the braces {, }
and hence very easily activated/deactivated.

R only knows about single line comments. There is no multi line comment.
If you wish to comment several lines you will have to prefix each line with #.
Your editor may provide means of prefixing several lines with # by selecting
lines and executing some command.
Rstudio provides Ctrl+Shift+C (Windows. Linux) and Cmd+Shift+C (OS X) on
selected lines.
And other editors have other shortcuts.
You’ll just have to get used to this.

Re: [R] How to use multi paragraph comment like /* and */ in cpp?
I don't understand what's your meaning, do you mean that i should do some file
processing,(like writing a script) ,so that i could add # in any line i
wanted.
I think it is not convenient.
And, it does seems that there is no way to multi line comment in R. But when i
turn to using Rstudio, after lots trying, i find that ctrl+shift+C can do the
thing.
Also i investgate roxygen, but it seems needing to learn the whole package ,
if some one happen to know how to do in roxygen, may you give me a quick
reference?

A workaround is to escape the evaluation of the lines. For example:

Re: [R] How to use multi paragraph comment like /* and */ in cpp?
There are no multi line comment markers in R. However, since you are always referring to RStudio you might want to look into roxygen, since their editor supports that tool. I would also suggest making more functions that are smaller. --- Jeff NewmillerThe . . Go Live... DCN:Basics: ##.#. ##.#. Live Go... Live: OO#.. Dead: OO#..
