This app creates samples from distributions you set. For the moment I am only doing Gaussian and continuous uniform distributions. There are situations in which you may need these data for use outside these apps but I created this app mainly to allow you to generate data that you might want to plug into other apps here.

You input data using the sidebar on the left to select the distribution you want and then the sample and population characteristics you want. The options for those depend on the distribution you want. Hit the 'generate' button when you have the specifications you want. The data come up in the tabs to the right, one gives them as a vector you can copy, the next as a single variable table that can be downloaded in various file formats.

If you have generated your sample this shows the same as a long table with two variables, the row number and then the values. The buttons at the bottom allow you to export the data.

Computation background

This uses the built in random number generation functions, currently rnorm() and runif() that are in the standard, i.e. attached by default, package 'stats'. This run used R version.

Rather than putting more about them here where they might get out of date, I suspect that if you want more detail, you are geeky enough to find the information by getting your own copy of R and using that or by searching on the internet.

Next please ...

Unless you are very familiar with it, please now go to the 'Background' tab and read the information there.

This shiny app is one of a growing number in, my shiny server
They complement:

my Rblog of posts about using R
the glossary linked with
the OMbook
the CECPfuns R package
and it's all part of the resources of PSYCTC.org
and linked with the CORE system web site

There is a form if you want to contact me: so do please use that if you think there is anything wrong here or anything that could be improved.

There is also now an Email announcement list, never updating more than monthly, where I will put up developments of new apps here, a summary of updates to the glossary and new posts in the Rblog. You can sign up for that here.
