Forest Plot for Cox Proportional Hazards Model
Drawing Forest Plot for Cox proportional hazards model. In two panels the model structure is presented.
ggforest( model, data = NULL, main = "Hazard ratio", cpositions = c(0.02, 0.22, 0.4), fontsize = 0.7, refLabel = "reference", noDigits = 2 )
model |
an object of class coxph. |
data |
a dataset used to fit survival curves. If not supplied then data will be extracted from 'fit' object. |
main |
title of the plot. |
cpositions |
relative positions of first three columns in the OX scale. |
fontsize |
relative size of annotations in the plot. Default value: 0.7. |
refLabel |
label for reference levels of factor variables. |
noDigits |
number of digits for estimates and p-values in the plot. |
returns a ggplot2 object (invisibly)
