Error {gsl} | R Documentation

## Error functions

### Description

Error functions as per the Gnu Scientific Library, reference manual section 7.15 and AMS-55, chapter 7. Thes functions are declared in header file `gsl_sf_error.h`

### Usage

    erf(x, mode=0, give=FALSE, strict=TRUE)
    erfc(x, mode=0, give=FALSE, strict=TRUE)
    log_erfc(x, mode=0, give=FALSE, strict=TRUE)
    log_erf_Z(x, mode=0, give=FALSE, strict=TRUE)
    erf_Q(x, mode=0, give=FALSE, strict=TRUE)
    hazard(x, mode=0, give=FALSE, strict=TRUE)

### Arguments

`x` | input: real values
`give` | Boolean with `TRUE` meaning to return a list of three items: the value, an estimate of the error, and a status number
`mode` | input: mode. For `GSL_PREC_DOUBLE` , `GSL_PREC_SINGLE`, `GSL_PREC_APPROX` use `0,1,2` respectively
`strict` | Boolean, with `TRUE` meaning to return `NaN` if status is an error

### Details

The zero functions return a status of `GSL_EDOM` and a value of `NA` for n≤q 0
