NA/NaN argument error when using raster:stack function

I have a raster with depth and I need to create a raster from it for incline and then stack the two rasters into a RasterStack. However I get this error:

Error in raster:stack(env, incline_rast) : NA/NaN argument

Here is my code:

#create incline raster from depth raster that is called env
incline_rast<-terrain(env,opt="slope")

## creating raster stack

stack <- raster:stack(env, incline_rast)
Error in raster:stack(env, incline_rast) : NA/NaN argument


stack <- raster:stack(env, incline_rast, quick = TRUE)
Error in raster:stack(env, incline_rast) : NA/NaN argument

The rasters have the same extent and coordinate system. What does this error mean and how to fix it? As I ma using R code to create one raster from another, why would it gve me an error?

How can I add information about the raster to make a reproducible example?

Try raster::stack(env,incline_raster).

You are using the single colon in a wrong context:

A single colon : is used to generate sequences, for example:

> 1:5
[1] 1 2 3 4 5

Whereas a double or triple colon ::& ::: is used to access exported and internal variables:

package::function

For more information have a look here or here.

Simply load the package beforehand with library(raster) or use the double colon :: notation.
