mean_sd | R Documentation |

`mean_sd`

takes as input either a) a numeric vector or b) a number for
the mean and a second number for the sd, and it outputs the mean plus or
minus the standard deviation of that vector with an appropriate number of sig
figs. If a vector was supplied, optionally also obtain the median, range, CV,
and/or 95

```
mean_sd(
x,
stdev.x = NULL,
calcRange = FALSE,
numDigRange = NA,
calcCV = FALSE,
calcMedian = FALSE,
calc95CI = FALSE,
reportn = FALSE,
ndig = NA,
na.rm = TRUE
)
```

`x` |
A vector of numbers |

`stdev.x` |
The sd when you want to provide it (leave as NULL if providing a vector of numbers) |

`calcRange` |
Should the range be reported? (logical) (TRUE or FALSE) |

`numDigRange` |
Number of digits to report for the range |

`calcCV` |
Should the coefficient of variation be reported? (logical) |

`calcMedian` |
Should the median be reported? (logical) |

`calc95CI` |
Should the 95% confidence interval be reported? (logical) If
calc95CI is set to TRUE, it will return the 95% confidence interval as
calculated as |

`reportn` |
Should the number of observations be reported? (logical) |

`ndig` |
Optionally set the number of sig figs to use if you don't want that calculated automatically |

`na.rm` |
Should NA values be removed when calculating the mean, standard
deviation, etc.? (logical) They'll still be included in the count of
observations if |

Example of ultimate output with all possible options set to TRUE:

5.1 (5) +/- 0.2 (4.7 to 5.3, 3.7%, 95%CI: 4.6 to 5.2, n = 18)

mean (median) +/- sd (range.min to range.max, CV%, 95%CI: lower to upper, n = n).

A few important notes:

I have not set this up to deal with mean values in scientific notation.

If

`sd(x) == 0`

, output will be unique(x).If you want to supply the mean and standard deviation and have this function return that with appropriate sig figs, you

*cannot*supply a vector of values for x and stdev.x. That does not work. If x is a vector of length > 1, the function will calculate mean, standard deviation, etc. rather than taking those values from a second vector. It will result in output, just not the*correct*output.

Returns a character string

```
mean_sd(rnorm(10, 5, 1))
mean_sd(rnorm(10, 5, 1), calcRange = TRUE)
mean_sd(rnorm(10, 5, 1), calcCV = TRUE)
mean_sd(rnorm(10, 5, 1), calcMedian = TRUE)
mean_sd(rnorm(10, 5, 1), calc95CI = TRUE)
mean_sd(rnorm(10, 5, 1), reportn = TRUE)
mean_sd(rnorm(10, 5, 1), calcRange = TRUE, calcCV = TRUE, reportn = TRUE)
```
