if_else2: if_else2

In cchsflow: Transforming and Harmonizing CCHS Variables

if_else2

Description

Custom ifelse function that evaluates missing (NA) values. If the logical argument (x) compares to a value that is 'NA', it is set to 'FALSE'

Usage

if_else2(x, a, b)

Arguments

x	A logical argument
a	value if 'x' is 'TRUE'
b	value if 'x' is 'FALSE'

Details

unlike the base ifelse() function, if_else2() is able to evaluate NA as either a or b. In base ifelse(), anything compared to NA will produce NA, which can break a function. When dealing with large datasets like the CCHS, there are many missing (NA) values. That means a special ifelse function like if_else2() is needed in order for other functions to not break

Value

a or b based on the evaluation of x

Examples

age <- 12
status <- if_else2((age < 18), "child", "invalid age")
print(status)

age <- NA
status <- if_else2((age < 18), "child", "invalid age")
print(status)
