Is there a way to create Bollinger Bands without having to loop on the observations of a time serie? Any help appreciated Thanks

I have the following function: Myfunc <- function(var1,var2,.....,varN) { ..... } In the above function I have a variable number of parameters (N>2). How can I count how many parameters have been entered? Any help appreciated Thanks Arno

I've the following problem: The below function runs a loop with regression analysis and stores F-Stat in a matrix. When I call the matrix elements (models[i,j]) in the function I get proper results, but when I try to call the same elements outside the function the matrix appears to be empty e.g when I call compt inside the function I get: 5 but when I call it outside I get: 1. This is the

I'd like to estimate time varying coefficients in a linear regression using a Kalman filter. Even if the Kalman Filter seems to be available in some packages I can't figure out how to use it to estimate the coefficients. Is there anyway to do that in R? Any help appreciated Thanks
