答复: [R] fail in adding library in new version.

[Ivy_Li]

Dear Gabor,
	Thank your for helping me so much!
	I have loaded R the newest version 2.1.1. Then I setup it in the path of D:\program files\R\ 
1. unpack tools.zip into c:\cygwin
2. install Active perl in c:\Perl
3. install the mingw32 in c:\mingwin
4. add "c:\cygwin; c:\mingwin\bin" in "Control Panel -> System -> Advanced -> Environment Variables -> Path -> Variable" (In your previous mail, you said "put these at the beginning of the path", I don't understand what is your meaning. Which path?) 

5. I tried an library example. I set a new folder named "example" in the "c:\MyRpackages\". And In the "example" folder, it contain an "DESCRIPTION" file and "R" folder. in "R" folder contain a "example" file. I just write very simple script in it:
a<-2; b<-3;sum <- sum(a,b); print(paste(a,"+",b,"=",sum))

6. I opened the DOS environment. Into the "D:\>"  Type the following code:
cd \Program Files\R\rw2010
But I don't understand the second line you writed in your previous mail: "bin\R cmd install /MyRPackages/example"

I am not sure that I set up R in "D:\" But I do so much action in C:\  Did I do the correct action? Did I do the action into the correct path?

I still need your and others help. Thank you very much!

Getting the latest version of R is strongly recommended.  The suggestions
below all assume the latest version and may or may not work if you do
not upgrade.

You may need to put these at the beginning of the path rather than the end.
Also just as a check enter 
     path
at the console to make sure that you have them.  You will likely
have to start a new console session and possibly even reboot.

Also you need the Microsoft Help Compiler, hhc.  Suggest
you reread the material on which tools you need.

In MyRPackages you would have a folder called example, in your case,
that contains the package.  Within folder example, you would have the
DESCRIPTION file, the R folder, etc.

You don't have to run R first.  You do need to make sure that R.exe can
be found on your path or else use the absolute path name in referring to R.
For example, if your path does not include R you could do something like this:

cd \Program Files\R\rw2010
bin\R cmd install /MyRPackages/example

Be sure to use forward slashes where shown above and backslashes
where shown.

Try all these suggestions including upgrading R and if that does not work
try posting screen dumps of the actual errors you are getting.
