How to transform NA values in to 0 in a raster layer

[GabrielYan]

I am currently working with climate data from Chelsa Database.
Their variables related to snow and frost have a problem that in places where it rarely or never snows variables have NA values instead of 0.
I can't use na.omit or something similar because it erases the cell from the raster, and then I can't work with the variable.
Does anyone have a solution to this problem?

Hi @GabrielYan , if the data is dtb,
Remmember put a reproducible example for better understand all the community.

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…

Try with this:

library(dplyr)
dtb<- dtb %>% replace(is.na(.), 0)

Hi, as mentioned, a reproducible example would help.
