Hi all,
I would like to use a loop for tasks that occurs repeatedly:
# Groups
# Umsatz <= 0: 1 (NICHT kaufend)
# Umsatz > 0: 2 (kaufend)
for (year in c("2011", "2012", "2013", "2014", "2015")) {
paste0("Kunden$Kunde_real_", year) <- (paste0("Kunden$Umsatz_", year) <= 0) *
1 +
(paste0("Kunden$Umsatz_", year) > 0) *
2
paste0("Kunden$Kunde_real_", year) <- factor(paste0("Kunden$Umsatz_", year),
levels = c(1, 2),
labels = c("NICHT kaufend",
"kaufend"))
}
This actually does not work due to the fact that the expression
"paste0("Kunden$Kunde_real_", year)" ist not interpreted as a variable name by
the R script language interpreter.
Is there a way to assembly variable names on the fly in R?
Regards
Georg
