Dear All, It is difficult to summarize the question in few words. So, please, look at the following example. Thanks in advance, domenico ---------------------------------------------------------------------------------------------------------------------------------------------------------- rm(list = ls()) posfix=1:5* 10 for(i in posfix) assign(paste("matX.",i,sep=""),matrix...

Dear All, is there a way to superimpose points and/or lines on a surface plot? Below I try to explain my problem. Suppose I have the following surface plot (likelikood for the normal variable when both parameters are unknown...

I know that there are packages implementings the probabilistic expert systems (the so-called probabilistic networks or bayesian networks). You find (at least) the following packages: bnlearn (bayesian network structure learning) deal (learning bayesian networks with mixed variables) G1DBN (for...

You should find the functions: bitAnd, bitOr and bitXor in the bitops package. Ciao, domenico mauede at alice.it wrote: > I cannot find any R function or operator that performs a binary AND operation, as performed by Fortran built-in...

From your post it is not clear how the data are organized. Supposing they are in a data frame you could use the ~ sintax. For example: timeColumn=as.Date("01-01-1970") + 1:500 timeSeries=rnorm(500) df=data.frame...

I am not sure to understand your problem, but it seems to me that you can use directly the function on the range of the dates: > x=as.Date(c('2007-01-01','2007-01-02')) > fff=function(x){y...

Dear HelpeRs, I am trying to use an thirdy-part library under Linux (the library is developed both for Windows and for Linux). I have tried different solutions (with the library developer) but we are not able to solve the...
