Dear Menne/ Jorge
Many thanks for the help rendered by you both.
Now, may I augment my problem.
While running the regressions (through 'for' loop), I tried to generate time
series plots for each iteration. Although the summary results from regressions
were saved in the output file (through sink() statement), yet the plots were
not saved. The tried code was:
x=read.table("sample.txt",header=T,sep="\t")
out="output.txt"
sink(out)
x
nm = names(x)
nm
for (i in 1:2)
{
for(j in (i+1):3)
{
formula= as.formula(paste(nm[i]," ~ ",nm[j],sep=""))
slr=lm(formula, data=x)
smr=summary(slr)
print(smr)
fit=fitted(slr)
tsp=ts.plot(fit)
}
}
sink()
Kindly help to get the plots saved, preferably in separate output files for
each iteration.
regards
ajss
