forest (meta) editing text
...n a meta-analsysis and all the forest (meta) and forestplot (rmeta) instructions assume you are doing a meta-analysis.
I found rmeta didn't play nicely for me so I'm using the meta package with forest. Here's some code that would allow you to reproduce it:
library(meta)
mydata.forest.DoseRed = data.frame(c(1,7,14,6,16), c(7,21,10,15,23), c(1,1,5,2,5), c(4,7,6,5,12))
colnames(mydata.forest.DoseRed)=c("n.DR","n.No.DR", "E.DR","E.No.DR")
rownames(mydata.forest.DoseRed)=c( "Age: 50-59", "Age: 60-69 ", "Age: >70",...

Fitting compartmental model with nls and lsoda?
...ribution here
# is hopefully to provide a starting point in "R" for people who
# have a pharmacokinetic modelling background.
# This text can be "cut and pasted" into R, or read in as a "source" file
# There are two differential equations in the system:
# V*dC/dt = Doserate - C*Cl + k21*A2 - k12*V*C
# dA2/dt = k12*V*C - k21*A2
# C is a dependent variable (Concentration in the central compartment)
# A is a dependent variable (Amount in the second compartment)
# t is the independent variable (time)
# V is the volume of the central compartment
# Cl is the clearance...
