Help in Plotting in "fArma" Package
What Dave said, plus here's a hint. Try this example (which uses base graphics):
plot(1:5)
plot(1:5, cex.lab=2)
Then look at the help page for par
help('par')
or
?par
to search for other graphics parameters (base graphics) you can use to change various things.
Success will depend, as Dave indicated, on how the package author handled the plotting options in rsFit().

Help in Plotting in "fArma" Package
The documentation say that additional arguments will be passed. I suspect this will be a base graphics plot. You should look at the code of plot.rsfit to determine which arguments get processed.

Value of Hurst exponent (R/S) method > 1
Hello,
I'm using fArma package to estimate the value of Hurst exponent using R/S
method. However, for a certain set of data I get H ~ 1.8. How do I
interpret this?
Following are the output that I get for this set:
> mean(data[,2])
[1] 400.5433
> sd(data[,2])
[1] 1139.786
>
> rsFit(data[,2], levels = 64)

regarding chaos
hi all,
I have a simple question that does power spectral analysis related to
capacity dimension, information dimension, lyapunov exponent, hurst
exponent.
If yes then please show me the way. I am newbie in the world of chaos.

Help in estimating HURST parameter
Hi,
Can u please tell me which all packages do i need to install to
estimate the hurst parameter in R. I have tried installing all the possible
options but still it doesnt work.
basically i want to use 9 functions to estimate hurst parameter like
aggvarfit, rsfit, etc.
i will be very thankful if u could be of some help.

Hurst Exponent Estimation
Dear All,
I am a novice when it comes to time-series analysis and at the moment I
am actually interested in calculating the Hurst exponent of a time
series.
This question has already been asked quite some time ago
http://bit.ly/98dZsi
and I trust some progress has been made ever since.
I was able to find some functions in the packages

Steps to determine Hurst exponent
Hello,
I'm using the fArma package to estimate Hurst exponent by R/S method. I've
some measurements in the following format:
Call_number Call_duration
I'm using the following steps. Am new to R, so it would help if someone
could please confirm if my steps are correct.
Further, this method seems to give a value H ~= 0.8 (> 0.5). Is the use of
R/S method to estimate H OK?

Help on time series & Hurst exponent
Hello,
I'm an absolute beginner with R. I'm hoping to do some time-series analysis
on my data. The data looks like
#time value

70 7
83 130
84 7
and so on where time could be in seconds or hours or days (not all at the
same time). How could I import such a file to R and do some simple stuff
(say plot the values)? As per the tutorials on time series, I could use the

A simple question.
I get some return from the R in my C++ program (via Rcpp package). The

Need help with pointLabels()
Hello R-list,
I am plotting a weighted linear regression in R. The points on my chart are
also scaled to sample size, so some points are large, some are small. I have
figured out everything I need using the plot() function: how to plot the
points, scale them by sample size, weight the linear regression by sample
size, plot that line, and plot the labels for the points. However, although

how to simulate a time series
Dear useRs,
I want to simulate a time series (stationary; the distribution of
values is skewed to the right; quite a few ARMA absolute standardized
residuals above 2 - about 8% of them). Is this the right way to do it?

Lo's modified R/S
Hi all,
Does anyone know if Lo's modified R/S statistic is implemented in R?
I found "rsFit" function from fArma package (LrdModelling), but I guess this
is to calculate the classical R/S statistic.
Thank you,
M.
