@DaveRGP I understand that and I already use data.table but these are all xlsb files and there is nothing I can do about it. They come in mails from different people and we arrange that In a folder. and they are not perticulary in order. So before i compile them into one big file I have check the column names and column types and other stuff like that so that I can arrange it.
I am sure many people can do it much better than I do but I just wanted to know 2 things. are there any fast readymade package for for loops and if I can use my knowledge of basic golang with R.
That's all I wanted to know nothing much.
And I really appreciate you taking time to read and answer my question. Thanks a lot. We can grow together as a community if we answer each other like this. Till we are active and open R will grow exponentially. I have full faith in the Language.
I just sometime doubt my own caliber and knowledge so I ask such stupid question just to see if there is any answer to it.
but thanks for responding. R studio should create the same sort of package for at least top languages like java, c, python, ruby, rust and golang. It will help people from different background adopt the R style and write new and advance packages in different languages. I feel just being a subset of c++ is not good. But then again they have their own economics of time and resources. I don't criticize it.
I just found 2 answers there is no package for writing faster for loops in R and for integrating R with Go.
But my takeaway is also that it has a good community.
