[R-pkg-devel] no visible binding for global variable ‘degree_C’ - CRAN check note

Hi Andrew, set_units(T, "degree_C") does not work;

however, setting
degree_C as a global variable does work.

Thank you for your suggestion.

You can declare degree_C as a variable before using set_units():

degree_C <- NULL
set_units(T, degree_C)

you could use globalVariables() somewhere at the top-level in your
package:

utils::globalVariables("degree_C")

or you could supply degree_C as a literal character string:

set_units(T, "degree_C")

In my iemisc package, I am using the units package.

This is an example of how I am using the set_units function:

T <- 20

set_units(T, degree_C)

Upon checking iemisc with devtools for CRAN submission, I receive the
following note under "checking R code for possible problems":

no visible binding for global variable ?degree_C?

Please tell me how to avoid that note in my R packages.

Thank you.
