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.
