average columns of data frame corresponding to replicates
Hi Group,
I have a data frame below. Within this data frame there are samples
(columns) that are measured more than once. Samples are indicated by
"idx". So "id1" is present in columns 1, 3, and 5. Not every id is
repeated. I would like to create a new data frame so that the repeated
ids are averaged. For example, in the new data frame, columns 1, 3,
and 5 of the original

I need to perform this simple sampling function several hundred times:

A question regarding bootstrap
Dear List Members,
I have two small samples (n=20), the distributions are highly skewed. Does
it make any sense to do a boostrap test to check for difference in means?
And if so, could this be done like this:
x <- numeric(10000)
for(i in 1:10000) {
x[i] <- mean(sample(sample1,replace=TRUE)) -
mean(sample(sample2,replace=TRUE))
}
(mean(sample1)-mean(sample2))/sd(x)

Random sample from a data frame where ID column values don't match the values in an ID column in a second data frame
Hello,
Let's say I've drawn a random sample (sample1.df) from a large data frame
(main.df), and I want to create a second random sample (sample2.df) where
the values in its ID column *are not* in the equivalent ID column in the
first sample (sample1.df). How would I go about doing this?
In other words:
The values in sample2.df$ID *are not found* in sample1.df$ID, and both
samples are
