TIm, thanks for replying to my questions. I really value your insights
in areas of statistics (small sample sizes, agricultural statistics)
that are unique.
The use of one method or technique to check the other was not one I had

I marked this posting as Off Topic because it doesn’t specifically
apply to R and Statistics, but is rather a general question about
statistics and the teaching of statistics. If this is annoying to you,

Hi, Richard, thanks for replying. I should have mentioned the third

Hello, all,
I'm learning to do randomized distributions in my Stats 101 class*. I
thought I could do it with a call to sample() inside a matrix(), like:

I'm trying to calculate the mean temperature max from a file of climate

Yep, that did it. I didn't know that you could have pipelines within
