get_summary_stats | R Documentation |
Compute summary statistics for one or multiple numeric variables.
get_summary_stats( data, ..., type = c("full", "common", "robust", "five_number", "mean_sd", "mean_se", "mean_ci", "median_iqr", "median_mad", "quantile", "mean", "median", "min", "max"), show = NULL, probs = seq(0, 1, 0.25) )
data |
a data frame |
... |
(optional) One or more unquoted expressions (or variable names) separated by commas. Used to select a variable of interest. If no variable is specified, then the summary statistics of all numeric variables in the data frame is computed. |
type |
type of summary statistics. Possible values include: |
show |
a character vector specifying the summary statistics you want to
show. Example: |
probs |
numeric vector of probabilities with values in [0,1]. Used only when type = "quantile". |
A data frame containing descriptive statistics, such as:
n: the number of individuals
min: minimum
max: maximum
median: median
mean: mean
q1, q3: the first and the third quartile, respectively.
iqr: interquartile range
mad: median absolute deviation (see ?MAD)
sd: standard deviation of the mean
se: standard error of the mean
ci: 95 percent confidence interval of the mean
