rf_summary: Create a rf.data.frame object

In graphPAF: Estimating and Displaying Population Attributable Fractions

Create a rf.data.frame object

Description

Create a rf.data.frame object for risk factors, prevalence and risk ratios. This will be used in fan plots and nomograms (by simply sending the rf.dat.frame object to plot)

Usage

rf_summary(rf_names, rf_prev, risk, log = FALSE)

Arguments

rf_names	A character vector of risk factor names
rf_prev	A numeric vector specifying prevalence of risk factor in disease controls (estimates of population prevalence can also be used if the disease is rare)
risk	A numeric vector of relative risks or Odds ratios for disease corresponding to each risk factor (if log=FALSE). Log-relative risks or log-odds ratios can be alternatively specified (if log=TRUE)
log	default TRUE. Set to TRUE if relative risks/odds ratios are specified on log-scale

Value

A rf.data.frame object

Examples

library(ggplot2)
rfs <- rf_summary(rf_names=c('Hypertension','Inactivity','ApoB/ApoA','Diet',
'WHR','Smoking','Cardiac causes','Alcohol','Global Stress','Diabetes'),
rf_prev=c(.474,.837,.669,.67,.67,.224,.049,.277,.144,.129),
risk=c(1.093,0.501,0.428,0.378,0.294,0.513,1.156,0.186,0.301,0.148),log=TRUE)
# fanplot
plot(rfs,fan.point.size=4,fan.label.size=4,
fan.legend.text.size=10,fan.legend.title.size=10,
fan.axis.text.size=10,fan.axis.title.size=10)
# nomogram
plot(rfs,nomogram.label.size=6,
nomogram.axis.text.size=6, type="n")
# reverse nomogram
plot(rfs,nomogram.label.size=6,
nomogram.axis.text.size=6, type="rn")
