It 's possible in R to predict the new values for a vector ?
For example I have these vectors
V1 at time 1 is [1 3 6 3 8 5 3]
V2 at time 2 is [5 3 7 8 9 5 4]
V3 at time 3 is [7 5 3 2In my absentmindedness I 'd forgotten to CC this to the list... and
BTW using gc() in the loop increases the runtime...

Hi there.
Is there any function in R to plot the probability-probability plot (PP
plot)? Suppose I am testing some data against normal.
Thanks.

I would like to know how to call sas code in R. Since I simulate data in
R and I need to use sas code (garch-t egarch and gjr) to estimate it. I
need to simulate 500 times with 2000 obs. HoWhile you are looking at weird distributions here is one that
we have used in experiments on noise masking to explore the

I want to generate two random variables (X1 X2) from uniform

Does anyone know how to do it in R?
Many thanks!

Dear List
I am generating a series of plots iteratively using Sweave. In short a
dataframe is subsetted row by row and variable graphics are created
conditional on the data in each row. In this parI have x y data on three animals (~150 data points each). I have calculated
the fixed kernel home range using the 'adehabitat ' library and the LSCV
smoothing factor. Can anyone provide me with som |
