All,
I've devised a way to toss a coin three times and record the number of heads,
then use the table command to summarize the number of time 0, 1, 2, or 3 heads
were obtained.
n <- 100
x <- sample(c("H","T"),3*n,replace=TRUE)
dim(x) <- c(3,n)
num_heads <- apply(x,2,function(x) sum(x=="H"))
table(num_heads)/n
What I'd like to do next is run this code 10 times, and gather the results in a
matrix with 10 rows and 4 columns, where the first row records the output of
the first run of the above code, the second row records the second run of the
above code, etc.
Looking for some simple ideas on how to accomplish this.
Thanks.
David
