I was able to read the data using the following code:
jd1 - read.table('Practicedata.dat',header=T,sep=\t,nrow=6240)
jd2 - read.table('Practicedata.dat',header=T,sep=\t,skip=6241)
colnames(jd1) - c(Date,Mod)
colnames(jd2) - c(Date, Obs)
p - ggplot(jd1,aes(x=Date,y=Mod))+geom_line()
p - p +
You have to sync up the data before you can do a scatter plot. If the data are
changing slowly relative to the sample rates then you can use approx to
interpolate one data set at the timestamps of the second to generate a column
you can add to the second data frame.

You're probably being killed by the overhead of parallelization which
is, in this case, far more than actual computation time. I've not dug
