bp_hist {bp} | R Documentation |
Blood Pressure Histograms
Description
The bp_hist
function serves to display the frequencies of the SBP
and DBP
readings. These histograms are formatted to complement the bp_scatter
function.
Usage
bp_hist(data, subj = NULL, bins = 30, na.rm = TRUE)
Arguments
data |
A processed dataframe resulting from the |
subj |
Optional argument. Allows the user to specify and subset specific subjects
from the |
bins |
An integer specifying how many bins to use for histogram plots. This is a ggplot parameter; default value set to 30 |
na.rm |
An logical value specifying whether or not to remove empty values from data frame. This is a ggplot parameter; default value set to TRUE. |
Value
A list containing four objects: three histogram visual graphics corresponding to
the SBP / DBP totals, SBP frequency, and DBP frequency, and a fourth list element
corresponding to a plot legend object for use in the bp_report
function
