output from STL
Hi All,
How do I can create a new vector, i.e. 'seasonal' or 'trend' from the
resultant seasonal or trend component of the Time.Series object produced by
STL, and how I could superpose in the same graphic, i.e. original data and
trend or seasonality?
Thanks in advance!

Hi,
How do I can make a lagged scatterplot of two variables:

more about ts and NA's
Hi,
I've seen that handle missing values makes difficult to manage data series
within R. I've look at Shumway's program (ASTSA) and Brockwell & Davis
pogram (ITSM), it seems that both handle NA's values without problem, or
maybe, I'm getting an spurious results?
My problem is with two variables: rain and river flow: the first has 7 NA
values (is to say, seven months, non

statistical help
Hi All,
Briefly, I belong to a fisheries research group. At this time I'm working
on my PhD and I'm looking for some statistical help. My mathematical and
statistical skills are still scarce, I've gathered many different types of
data (landings, climate and upwelling indexes, rains, etc) and I wonder
about what kind of statistical procedure use with them. I'm a little
confused

eigenvectors order
Hi,
How the eigenvectors output by the eigen() function are ordered. The
first column corresponds to the largest eigenvalue? or is the last
column as in Octave?
I'm performing a spatial-temporal analysis of some climatic variables
so my matrices are MxN (locations*time)and I'm looking for the leading
EOF's. As I have understand the eigenvectors columns represent those
EOF's

Dear Sirs,
I am an economist, and I have learned about R from an statician.
I would like to get some instructions on which packages of R should I
install. I am intending to use R for graphical analysis, correlaction, and
also estimation - this latter the least, since I have an econometric
package which performes it very well. I should also mention that I am going

about s.window in stl
Hi,
Is there anybody who could explain a little bit the use of s.window and
t.window in STL. If I decompose a series using the default values, I get a
very irregular trends, but if I play with the options, I get less rare
trends. If anybody can explain me the concepts behind these options I will
appreciate a lot. I'm not a mathematician ;-)
Thanks in advance
Cheers,

He realizado un dredge (para obtener todos los modelos GAM posibles a parir

A mí también me resulta raro, porque no me pasa siempre. Es un poco

estará relacionado, claro, pero no consigo averiguar a qué se debe.
Además las pruebas que hago me dejan todavía más perplejo.
