Hello,
I wonder if someone can elaborate on why in the first graph I am able to set
labels vertical to the x-axis but not in the second.
I tried to select the window but it didnt really help.
Many Thanks

the more general thing I'd like to learn here is how to compute Function of

In terms of the reason why I am interested in this, I need to compute the

Hello,
I would like to create lagged and delta variables from a set of variables
and then add them to a dataframe
Suppose that GDPPcSa is a variable. I would like to be able to do this
QuarterlyData$D1GdpPcSa = diff(GDPPcSa , 1)
in an automated fashion so that I loop over Quartely data to compu
Hello,
quick question I reckon.
Is there a way to add to time series to a dataframe without knowing their
name in advance?
I can figure it out the following but wondered if there is a better way
Thanks

Hello everyone,
I am experiencng some problems in producing forecasts and backcast from an

Hi list,
I would like to estimate and forecast the seasonal component of a series. My
model which uses daily data would be something y t = alpha + beta x SeasComp
t + gamma x OtherRegressors t.
One approach to this would be use quarterly dummies, another to use a sine
function. The first would c

Intercept is significant and I suppose it should be used if I want simulate

Hi,
I have been looking at arima.sim to simulate the output from an ARMA model
fed with a normal and uncorrelated input series but I cannot find a way to
pass an intercept / constant into the model. In other words, the model input
in the function allows only for the AR and MA components but I need

Hi Everyone,
quick question before the end of the year.
I have soem indices to select data from a bigger sample. I want to select n
days before each index and n days after the index. Any clever way to do it.
A for loop would do but I wanted to know if there is a moreR-friendly way to

I would like to know how to turn a variable into a string. I have tried
as.symbol and as.name but it doesnt work for what I'd like to do
Essentially, I'd like to feed the function below with two variables. This
works fine in the bit working out number of elements in each variable.
In the print(sp
Awesome - thanks!

Is there a way to pass an additional parameter to apply?

Hi,
Can anyone suggest a clever way to compute a rolling weekly average of the
columns in a matrix? The column bit is straightforward use apply given a
function which does what you want on a column. With regard to a particular
column, the obvious way is to run a for loop indexing the last 7 day
