[R] Problem with global variable building a package

[Eva Prieto Castro]

Hi,

 

My name is
Eva and this is my first message here. My English is not very good, but I hope
you can understand my question, in the context of an academic project.

 

I have
developed several functions in R and the
idea is that the user can access functions in order to:

 

1)     
Alter
parameters in relation with data and type of analysis.

2)     
Run
statistical analysis (Text and pdf files with results will be generated).

3)     
View
the value of the most important parameters.

 

All the
parameters I need are stored in a list object, and this list is used in all the
functions along the cycle performed by the user, but I would like the user does
not need to pass the name of the list as argument when he/she runs the different
functions, so I think I need to treat the list as a global variable.

 

Firstly, I
used the global assignment operator (“<<-“); secondly, I used “get” and 
“assign”
functions and even I used a new.env() in order to use a new environment
exclusively for my list. However, when I try to build a package with all my
functions I don’t reach this end, because of an error in parse process.

 

My question
for you is the following: taking into account that my end is to build a
package, what can I do with this “global” list?. How can I treat it?.

 

Thanks in
advance.

 

Regards,

Eva
