Replace NA with 0 in R (Example)

This tutorial shows how to replace NA values with zero in the R programming language.

Example Data

vec <- c(2, NA, 5, NA, 8, 3)   # Create example vector
vec                            # Print example vector
# 2 NA  5 NA  8  3

Replace NA with Zero in R

vec[is.na(vec)] <- 0           # Replace NA with 0
vec                            # Print updated vector
# 2 0 5 0 8 3

In the previous example, we changed NAs of a vector to 0. However, we can apply the same operation to a data frame column.
