if_else2 | R Documentation |
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'
if_else2(x, a, b)
x |
A logical argument |
a |
value if 'x' is 'TRUE' |
b |
value if 'x' is 'FALSE' |
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
a or b based on the evaluation of x
age <- 12
status <- if_else2((age < 18), "child", "invalid age")
print(status)
age <- NA
status <- if_else2((age < 18), "child", "invalid age")
print(status)
