Dear Matthias,
you could try something like:
x <- matrix(rnorm(30*6), 30, 6)
colnames(x) <- c("Besch", "Ang.m", "Arb.m", "i10", "Umsatz", "arbstd")
your.choice <- "Besch"
x[,match(your.choice, colnames(x))]
x[,-match(your.choice, colnames(x))]
I hope this helps.
Best,
Dimitris

access my data frame without variable "Besch", or is there any better
solution.
