R help - Sep 2009 - finding the minimum value

Hi all,
I'm using a certain  procedure to calculate the value of some variable(Bayes
risk),B.
So I got the values B1, B2, ........, B1000, each under certain input values and
using a long procedure.
Now, I want to put the values I got in a nummerical vector and find their
minimum value. I think c( ) should work.For example if I have only 10 values I
could have used
c(B1,B2,B3,B4,B5,B6,B7,B8,B9,B10)
But how can I do this for 1000 values?
I think the question is really trivial, but I tried to work on it and
couldn't reach anythg.
Thanks.
Maram

 	sapply( paste( "B", 1:1000, sep='' ), get )

but I wonder why you didn't store the values in a list to start with.

Hi,

If I correctly understand what you want to do, then this might work:
> tmp <- rep(0, times=1000)
> for (i in 1:1000) tmp[i] <- get(paste('B', i, sep=''))
> mean(tmp)
HTH,
