p |
a ggplot on which you want to add summary statistics. |
fun |
a function that is given the complete data and should return a data frame with variables ymin, y, and ymax. Allowed values are one of: "mean", "mean_se", "mean_sd", "mean_ci", "mean_range", "median", "median_iqr", "median_hilow", "median_q1q3", "median_mad", "median_range". |
error.plot |
plot type used to visualize error. Allowed values are one of
|
color |
point or outline color. |
fill |
fill color. Used only whne |
group |
grouping variable. Allowed values are 1 (for one group) or a character vector specifying the name of the grouping variable. Used only for adding statistical summary per group. |
width |
numeric value between 0 and 1 specifying bar or box width.
Example width = 0.8. Used only when |
shape |
point shape. Allowed values can be displayed using the function
|
size |
numeric value in [0-1] specifying point and line size. |
linetype |
line type. |
show.legend |
logical. Should this layer be included in the legends? NA,
the default, includes if any aesthetics are mapped. |
ci |
the percent range of the confidence interval (default is 0.95). |
data |
a |
position |
position adjustment, either as a string, or the result of a call to a position adjustment function. Used to adjust position for multiple groups. |
x |
a numeric vector. |
error.limit |
allowed values are one of ("both", "lower", "upper", "none") specifying whether to plot the lower and/or the upper limits of error interval. |
add_summary()
: add summary statistics onto a ggplot.
mean_se_()
: returns the mean
and the error limits defined by the
standard error
. We used the name mean_se_
() to avoid masking mean_se
().
mean_sd()
: returns the mean
and the error limits defined by the
standard deviation
.
mean_ci()
: returns the mean
and the error limits defined by the
confidence interval
.
mean_range()
: returns the mean
and the error limits defined by the
range = max - min
.
median_iqr()
: returns the median
and the error limits
defined by the interquartile range
.
median_hilow_()
: computes the sample median and a selected pair of
outer quantiles having equal tail areas. This function is a reformatted
version of Hmisc::smedian.hilow()
. The confidence limits are computed
as follow: lower.limits = (1-ci)/2
percentiles; upper.limits =
(1+ci)/2
percentiles. By default (ci = 0.95
), the 2.5th and the
97.5th percentiles are used as the lower and the upper confidence limits,
respectively. If you want to use the 25th and the 75th percentiles as the
confidence limits, then specify ci = 0.5
or use the function
median_q1q3()
.
median_q1q3()
: computes the sample median and, the 25th and 75th
percentiles. Wrapper around the function median_hilow_()
using
ci = 0.5
.
median_mad()
: returns the median
and the error limits
defined by the median absolute deviation
.
median_range()
: returns the median
and the error limits
defined by the range = max - min
.
