[R] Seeking help in Package development

[Nipesh Bajaj]

Thanks Gabor for your input. Here what I have done is that:

1. Copy 'MyPackage' folder (developed by package.skeleton) into
'C:\Program Files\R\R-2.12.1\bin' (I found R.exe is there)

2. In the command prompt, I changed the working directory using "CD"
command and run 'R CMD build MyPackage'

3. I have seen that a file named 'MyPackage_1.0.tar' has been created.
Then I pasted that file in ''C:\Program Files\R\R-2.12.1\bin'

4. Again run R CMD INSTALL MyPackage_1.0.tar.gz. However here I got
some error saying:
'Error in Rd_info(db[[i]]) : Rd files must have a non-empty \title'

In my Package, there are 2 user defined functions MyFunction1 &
MyFunction2, 1st function just get the length of it's argument and 2nd
function get the Range. I have modified the manual pages of those 2
functions as (just 1st few lines):

\name{MyFunction1}
\alias{MyFunction1}
%- Also NEED an '\alias' for EACH other topic documented here.
\title{
  ~~(Title) This function try to get the length of it's arguments ~~
}
\description{
  ~~ (Description) This function try to get the length of it's arguments ~~
}
\usage{
MyFunction1(x)
}

\name{MyFunction2}
\alias{MyFunction2}
%- Also NEED an '\alias' for EACH other topic documented here.
\title{
  ~~(Title) This function try to get the range of it's arguments ~~
}
\description{
%%  ~~ A concise (1-5 lines) description of what the function does. ~~
}
\usage{
MyFunction2(x)
}

I understand there is something to do with the 'title' segments of any
(or all) those 2 functions. However could not find what to do. Any
point please?

Actually I wanted to create .zip file as I am working in Vista. For
that I have intalled R_tool as well. However I could not understand
how I can use that. Any help will be highly appreciated.

Thanks,
