I have done that, and sure enough when the package is loaded, the
structure is there. However, when I am working on debugging code, and I
refer to the structure in a function, RStudio gives a warning that the
structure is out of scope, say the data frame is myDF:
myFunc <- function(myIndex) {
junk <- myDF[index]
return(junk)
}
Have you tried the following:
myFunc <- function(myIndex) {
junk <- yrPkg:::myDF[index]
return(junk)
}
This will turn of similar messages is slightly different
contexts. I don't know if it will work here (and I don't have time to
try it myself now). Spencer Graves
RStudio will warn that myDF is out of scope. My question is if there is a
proper way to refer to myDF so as not to get the warning, or just ignore
it. Basically before submission I try to remove all warnings from the
editor, even style ones, just to have things cleaner.
