Link from "alpha" also

Could be useful to have an explanation about pivot functions pivot_longer() and pivot_wider(), linking to the definitions for long and wide.

Typo: "the conventional a t-test" should be "a conventional t-test"

Needs an example

1. add rmd
2. TBD

Secondary definition for alpha in the context of ggplot

Secondary definition for Cronbach's alpha

TBD - would be good to add something about the idea of the library and loading packages into the library.

Example needs explanatory text

Packages that are required to run another package. R should automatically install these for you when you install a new package.

1. Add .Rmd
2. TBD

1. to add .Rmd file
2. TBD

To be Added:

Propose: the number of observations that are free to vary to produce a known outcome

Basic example: If you run 5 people and ask them their age, and you know the mean age of those 5 people is 20.1, then four of those people can have any age but the 5th person must have a specific age to maintain the mean of 20.1. So the mean age here is the known outcome and four peoples age can vary freely (so your degrees of freedom is 4) but one person's age must be a specific number to maintain the known outcome.

Alternatively we could use something from the t-distribution and show how changing the df changes the probability of the outcome on the t-distribution.

in the context of Shiny content

1. add Rmd
2. TBD

in the context of backslashes creating literal versions of symbols that have a special meaning.

Definition of term "list" uses the term "container" (container data type) which links to C category in Glossary but definition for it doesn't exist yet.

Would be good to include maybe a paper on detecting outliers as well

Might be an idea to have a function that displays the definition of a word in the actual body of text in a paragraph, rather than the word. Say for example:

"Degrees of Freedom is defined as r glossary_show_definition("degrees of freedom")

Which would knit as:

"Degrees of Freedom is defined as The number of observations that are free to vary to produce a known outcome."

though might need to put a tolower() around it. That way people would only need to update the definition in the glossary and it would update in other places it is used and remove any inconsistencies. Might not be frequently used but could be handy.

TBD - would be good to add something about conflicts in function names

A description of what a model does/its aims. Could link to examples like glm and glmm.

Define formula in the sense of R's object type?

1. Rmd Needed
2. TBD

Would be useful to define the environment - maybe linking to definitions for objects and variables.

Needs an example

1. Add .Rmd
2. TBD

Needs more detail and links to papers/resources

explain how to remove NAs for calcs like mean, sd, cor

Example or extended definition

ToBeAdded.

Suggestion:

Data Visualisation is the skill of creating and interpreting plots and figures from data.

In the context of Shiny content

link to knit

TBD

Suggested: "when two or more values/observations within a variable are identical and assume the same rank order value"

Needs an example

Could be useful to define permutation tests and maybe link to Monte Carlo?

TBD - add a section on what is a boolean expression and give examples.

1. Add RMD
2. TBD

TDB

Additional comment or example about using whitespace in APA write-up. e.g.

with whitespace: t(df) = t-value, p = p-value, d = d-value

without whitespace: t(df)=t-value, p=p-value, d=d-value

Typo: "noraml"

Overview of joins and link to :

• binding joins
• filtering joins
• mutating joins

Also separate entries for semi_join, anti_join, left_join, right_join, inner_join, outer_join that link to their join type.

1. Add .Rmd
2. TBD
