R help - Apr 2014 - conditional probability removal

Greetings,

I would like to randomly remove elements from a numeric vector but with
different probabilities for higher numbers.

For example:

dat <- sample(seq(10), 100, replace=T)

# now I would like to say randomly remove elements but with a higher chance
of removing elements >= 5 and even greater for elements >= 8.

I am unfamiliar if there is a way to define conditional probabilities.  Any
insight would be appreciated.

Regards,
Charles

I think the discussion in this thread
  https://stat.ethz.ch/pipermail/r-help/2014-April/368816.html
applies exactly.

See the parameter "prob" of sample.

Cheers,
B.
