## Drawing a PSYCTC.org logo (and other circular things)

As title says: very simple stuff about circles in ggplot, does open up somne ideas about drawing therapy groups.

## Derangements #2

Follows on from 'Scores from matching things'

## Scores from matching things

Mostly about the method of derangements but some huxtable!

## Reading data into R from M$oft Access mdb

Work in progress about reading data from M$ mdb file into R

## Exact confidence intervals for difference between proportions

This describes the ExactCIdiff package, unpacks the arguments to the functions, looks at timings and notes an oddity, a typo I think, in the original paper about the package.

## Pre/post analyses

Teaching myself about pre/post therapy change analyses using R.
Probably the first of a series of posts.

## Chance corrected agreement

Simple plotting of raw agreement and Cohen's kappa for various prevalences of the rated quality
and only chance agreement

## Data ellipses and confidence ellipses

This just clarifies the distinction between a data ellipse and a confidence ellipse,
i.e. an ellipse describing the joint confidence intervals on two parameters of a model

## Compiling packages reporting missing headers in windows

For anyone else who hits this and doesn't want to wait for someone to put
the compiled package into CRAN

## OMbook_glossary

Code used for entries in the glossary for the OMbook

## Subscale/total correlations

A look at subscale/total correlations in the null model

## Spearman-Brown formula

How does internal reliability relate to number of items?

## Compiling R on a Raspberry Pi 4

I thought I should document this process as it turned out to be fairly easy

## Where to store different settings in Rmarkdown files

This may be of use to others but it's partly for me as I keep forgetting these and searching around for the .Rmd files in which I used the one I want!

## Wisdom of years!

I've learned a lot about data analysis from my errors, here's what I wish I'd known earlier!

## Making the CECPfuns package: my own usable package

This is very much work in progress so look for later posts about CECPfuns as well as this.

## More piping, and rowwise()

This extends https://www.psyctc.org/Rblog/posts/2021-02-07-why-pipe-why-the-tidyverse/ and introduces rowwise()

## Why pipe? Why the tidyverse?

A short description of the post.

## How I've done this

Just documenting how I have created these pages

## Bootstrap_Spearman

A quick exploration of bootstrapping a Spearman and why you might, or might not, want it.

## Handling overprinting

This is the first of my blog posts here, about the issue of overprinting and some ways to handle it
using R and ggplot(). There's a small spin off topic on the impact on bivariate correlations and on
linear regression of discretising continuous variables.

## Nudging groupings on plot axes

How to nudge categories on an axis of a ggplot plot.

## Welcome to CE Rblog

Welcome to my blog which I hope will be useful to people using R to analyse data
