Writing output to a file in a loop
Hello,
My problem is, that I have to build hundreds of GARCH models to obtain
volatility forecasts. I would like to run a loop, that would build those
forecasts for me. There is no problem, with writing only the results of
the forecasts, but I'd like to have stored results of the models in some
file, that I could check later, what are the models like, to be able to
compare if I should use

Regarding multiple axes in plots..
Hello,
I'd like to draw 2 plots in one graph.
Here is my code:
plot(data_min1$macd,main="1 min MACD",type="l")
lines(data_min1$macdsig,col="red")
par(new=T)
plot(data_min1$macdhist,type="h",main="")
axis(4)
par(new=F)
It seems it works.
But left axes of two graphs are over-drawn.
Could you let me know how to fix it ?

Need to study and learn about better plots
Hi,
So far my plotting needs have been sort of ignored as I got
acquainted with R this week, but now that I have the basics in place
for the program I wanted to write it's time for me to start learning
about how to make output that better suits my needs. I think I have
two sort of charts I need to concentrate on learning how to produce:
1) Probably a trivial request - a single chart that

possible TZ bug in parseISO8601 - "Error in if (length(c(year, month, day, hour, min, sec)) == 6 && c(year, : [...]"
Hey all,
Virgin post to this list - hope I've got it right ;o)
I've been learning R intensively the last two weeks and gone from newbie
status to *reasonably* comfortable with it.
Here's an issue I just cannot solve however as it appears to be some kind
of bug in R itself. But I won't claim that for sure.
I have a function as follows:
FindHighRow <- function(searchVector,
