`prop.trend.test (birthweight2$lbw2 ,birth

I am using R3.0.2 on a windows 64 bit machine. I building a .rnw file
from an .r file. I am using MikTex as the engine for latex. The
function dtaStata <- read.dta("core2.dta", convert.dates=TRUE) works
well in .R but; When I try reading a dta (stata) file I get an error
"subscript out of bounds".
variables in the above
case temp axilla.
The above code plot count of temp_axilla yearly,how can I include
serialno to be part of the plot?
I have used
library(ggplot2)
library(foreign)
utils package
