Missing Values in Logical Expressions
Hi All,
I need to evaluate missing values in my data. I am able to filter these
values and do simple statistics on it. But I do need new variables based
on variables with missing values in my dataset:
Check_Kunde_2011 <- ifelse(is.na(Umsatz_2011) == TRUE & Kunde_2011 == 1,
1, 0)
Check_Kunde_2011 <- factor(Check_Kunde_2011, levels = c(1,0), labels =
c("Check", "OK"))
The new variable is not correctly created. It contains no values:
table(Check_Kunde_2011)
< table of extent 0 >
I searched the web but cou...

Based on Jim's data your construction gives me correct result.
