R Warning message : is.na() applied to non-(list or vector) of type ‘builtin’ (2 Examples)

In this tutorial you’ll learn how to avoid the warning message : “is.na() applied to non-(list or vector)” in the R programming language.

Example 1: Replicating the Warning message : is.na() applied to non-(list or vector) of type ‘builtin’

is.na(sum)                     # Apply is.na to function name
# [1] FALSE
# Warning message:
# In is.na(sum) : is.na() applied to non-(list or vector) of type 'builtin'

Example 2: Fixing the Warning message : is.na() applied to non-(list or vector) of type ‘builtin’

vec <- 1:5                     # Construct some example data
vec                            # Print example data
# [1] 1 2 3 4 5

is.na(vec)                     # Apply is.na to data object
# [1] FALSE FALSE FALSE FALSE FALSE
