You did not follow the posting guide, did you use pure ascii email, and 
used illegal characters in your source code.  This caused extra work. 
Once I cleaned up your characters and made the example self-contained, 
the labels worked fine for me.  Here's the cleaned-up code:

x1 <- runif(20)
x2 <- runif(20)
y <- sample(0:1, 20, TRUE)
label(x1) <- 'A'
label(x2) <- 'B'

ddist <- datadist(x1,x2)
f <- lrm(y~x1+x2)
x<-nomogram(f, fun=function(x)1/(1+exp(-x)),
