barplot x-axis problem
Hi R-users,
I'm new to R and I'm trying to make a barplot combined with two lines
(refering to secondary y-axis). Bars should represent the number of
transfused patients by age class and sex and lines should represent
the amount of blood units given in age classes. I have now successfully made
a barplot and used par(new=TRUE) to plot another empty graph at the top of
the barplot.

A coding question involving variable assignments in ifelse()
Dear List,
Below is a simple, standard loss model that takes into account the
terms of an insurance policy:
deductible <- 15
coverage.limit <- 75
insurance.threshold <- deductible + coverage.limit
tmpf <- function() {
loss <- rlnorm(rpois(1, 3), 2, 5)
sum(ifelse(loss > insurance.threshold, loss - coverage.limit,
pmin(loss, deductible)))
}
net <- replicate(1000000, tmpf())

how to evaluate a dynamic variable?
Please help me evaluate a "dynamic variable" as show in the code
snippet below.
# regular variable
a = c(1,2,3,4)
# dynamic variable set at runtime
DV = "a"
eval(DV)
--> a
eval(eval(DV))
--> a
# what I want
something_goes_here(DV)
--> 1,2,3,4
Can someone teach me how to do this? Thanks very much.

Randomising matrices
I would like to be able to randomise presence-absence (i.e. binary)
matrices whilst keeping both the row and column totals constant. Is
there a function in R that would allow me to do this?
I'm working with vegetation presence-absence matrices based on field
observations. The matrices are formatted to have sites as rows and
species as columns. The presence of a species on a site is
