## One sample t-test for a vector

### Description

One sample t-test for a vector.

### Usage

    ttest1(x, m, alternative = "unequal", logged = FALSE, conf = NULL)

### Arguments

`x` | A numerical vector with the data.
`m` | The mean value under the null hypothesis.
`alternative` | The alternative hypothesis, "unequal", "greater" or "less".
`logged` | Should the p-values be returned (FALSE) or their logarithm (TRUE)?
`conf` | If you want a confidence interval supply the confidence level.

### Details

The usual one sample t-test is implemented, only faster.

### Value

A list including:

`res` | A two valued vector with the test statistic and its (logged) p-value.
`ci` | In the case you supplied a number in the input argument "conf" the relevant confidence interval will be returned as well.
