Dear Manoj,

Did you already give RStudio a try?

https://support.rstudio.com/hc/en-us/articles/200486488-Developing-Packages-with-RStudio

I find the tool relatively easy to use. But it also helps to read the instructions on the R website...

https://cran.r-project.org/doc/manuals/r-release/R-exts.html

Do you intend to release your package on CRAN? If that is the case, your package will have to comply to strict criteria.

If you have specific problems or questions you run into, I'm always willing to help...

Kind regards,

Pepijn

Dear Pepijn, 

First I thank you for giving me the response. If what I have doubt is the basic knowledge required to write in the programming language for R package.

Regards, 

Manoj

Dear Manoj,

In that case, I'm afraid I'm not able to be of much help. Developing an R package can take considerable time, which I cannot spare at the moment. Do note that it can be very beneficial for yourself to learn the R language properly. There is plenty of free material out there for self-education. All it takes is time (if you have some).

In any way, I wish you the best in finding the help you need.

Kind regards,

Pepijn
