## Correlation tools

### Description

Helper functions to compute important statistics from correlation coefficients.

### Usage

```r2z(r)

z2r(z)

r2t(r, n)

r2p(r, n)

rconfint(r, n, alpha = 0.05)

compcorr(r1, r2, n1, n2)
```

### Arguments

 `r, r1, r2` a correlation value `z` a Z-score `n, n1, n2` sample sizes `alpha` the significance level to use

### Functions

• `r2z()`: converts correlation coefficients to z-scores

• `z2r()`: converts z-scores to correlation coefficients

• `r2t()`: Converts correlation coefficients to t-scores

• `r2p()`: Computes the two-sided p-value for a given correlation

• `rconfint()`: Computes confidence intervals for a given correlation coefficient

• `compcorr()`: computes the significance of the difference between two correlation coefficients

cormean, multiple.cor, partial.cor

### Examples

```z <- r2z(.5)
r <- z2r(z)
t<-r2t(r,30)
r2p(r,30)
print(rconfint(r,30))
print(compcorr(.5,.7,20,20))
```
