Dear R helpers,
I've successfully created a package 'constants' using package.skeleton
() with one dataframe and a few functions. However, now that I want
to add some functions and data to the package, I run into a problem.
I ran prompt(...) and moved + edited the resulting .Rd files as
appropriate (I believe). The log file from RCMD check constants does
indicate a few problems (full log below).
As far as I understand, the real problem would be on the lines:
> * checking R code for possible problems ... NOTE
> L2eV: no visible binding for global variable 'Constants'
> eV2L: no visible binding for global variable 'Constants'
These two functions use the dataframe "Constants", part of this package:
> `L2eV` <- function(lambda)
> {
> data("Constants")
> Constants$h*Constants$cel/Constants$ee/lambda ->eV
> eV
> }
and
> `eV2L` <- function(eV)
> {
> data("Constants")
> Constants$h*Constants$cel/Constants$ee/eV ->Lambda
> Lambda
> }
After searching the R archives about "no visible binding for global
variable ", I added the quotes around "Constants" but it doesn't seem
to help. What would be the correct way to use this data inside the
package?
Best regards,
baptiste
