Various useful functions for working with data and writing functions

## Install

Install from CRAN

```{r, eval=FALSE}

## from CRAN repo

install.packages("tfse")

```

Install dev version from Github

```{r, eval=FALSE}

## from github

remotes::install_github("mkearney/tfse")

```

## Usage

### Scales

Rescale to standard (0-1) scale

```{r}

## 0-1 scale

rescale_standard(-2:2)

```

Rescale to normal (mean = 0; sd = 1) scale

```{r}

## z scores

rescale_normal(-2:2)

```

Rescale to arbitrary lower/upper bounds

```{r}

## specify new scale bounds

rescale_pointscale(-2:2, 1, 10)

```

### Citations

Print out the APA-formatted citation for R packages.

```{r}

## print out APA citation for {rtweet}

apa_citation("rtweet")

```

### Annotate script files

Use `box_code()` to add a header-like chunk to your clipboard–paste in script as desired.

```{r}

## store text in clipboard

box_code("EXAMPLE #1")

## the pasted output:

##----------------------------------------------------------------------------##

##                                 EXAMPLE #1                                 ##

##----------------------------------------------------------------------------##

```

### Regular expressions

Get all regular expression matches (using easier looka-heads/look-behinds)

```{r}

## some text

x <- c("This *is* a test", 

  "#this *was* a test", 

  "This *will* be a test!",

  "This *has been* a test; it *is* great.")

## return text between asterisks, return as atomic vector

regmatches_(x, "(?<=\\*)\\S[^*]+(?=\\*)", drop = TRUE)

```

### Github

Figure out the name of a Github repo for a given package

```{r}

## repo name of devtools

desc_gh_repo("devtools")

```

Convert a Github link to the raw URL version

```{r}

## path to raw version of Github file

github_raw("https://github.com/mkearney/driven-snow/blob/master/theme/driven-snow.rstheme")

```

## Help

View the help documentation

```{r, eval=FALSE}

## view R help documentatoin

help(package = "tfse")

```

## about tfse

- This is my personal R package of utility functions

- Why *tfse*? The acronym was creatively reconfigured from its

  originally intended state
