Package issues

[bweedop]

I feel like this should be simple but I am missing something. My plants.r is calling for the 'terrain' matrix that originates from my terrain.r. When I do R CMD check, I get a note telling me that 'no visible binding for global variable: terrain'
How do I go about solving the problem of having an object on one .r and then using it on another .r without causing problems with the check?

1. No variables in a package, only functions. It sounds like you are doing
   this.
2. Make sure you have used @export on all your functions

Sorry to be brief it's 6pm I'm on the train

I don't think I have any variables in the package. The issue is that I have my run.eco function using the terrain matrix:
run.eco<-function(timesteps, ...){ plants <- array("", dim=c(dim(terra),timesteps+1)) for(i in seq_len(dim(plants)[3])) plants[,,i][is.na(terra)] <- NA for(k in (seq_len(dim(plants)[3]-1))) plants[,,k] <- plant.timestep(plants[,,k], info) k<-k+1 return(plants) }
and R CMD check checks my example:
plants<-run.eco(10)

The check gives me an error saying: object 'terra' not found

Right, I see. There is a bug in this function. You're using terra - is it
an argument to your function?

Right now it is not but I tried using it as an argument and it gave me the same error...
