Description Usage Arguments Value References Examples

The following three functions can be used with missing data. They return the mean, the standard error of the mean and the confidence interval of the mean. Note that we hesitated to provide these functions: you should deal with missing data prior to making your plot.

1 2 3 4 5 | ```
meanNArm(x)
SE.meanNArm(x)
CI.meanNArm(x, gamma)
``` |

`x` |
a vector of numbers, the sample data (mandatory); |

`gamma` |
a confidence level for CI (default 0.95). |

the means, a measure of precision (SE) or an interval of precision (CI) in the presence of missing data.

1 2 3 4 5 | ```
# the confidence interval of the mean for default 95% and 90% confidence level
meanNArm( c(1,2,3, NA) )
SE.meanNArm( c(1,2,3, NA) )
CI.meanNArm( c(1,2,3, NA) )
CI.meanNArm( c(1,2,3, NA), gamma = 0.90)
``` |
