...ction doesn't have a "verbose" parameter. Thus, I can't disable it using a verbose parameter. I'm sure that there must be some procedure in R to do it but after searching through the mailing lists I haven't found anything about it. Thank you for your help, Miguel Rat?n Almansa

I've calculated as follows: matusita<-function(f1,f2,lw,up){ fmatu<-function(x) ( sqrt(f1(x)) - sqrt(f2(x)) )^2 sqrt (integrate( fmatu, lower=lw, upper=up, subdivisions=1000000)$value) } Josué Almansa Unitat de Recerca en Serveis Sanitaris Institut Municipal d'Investigació Mèdica, IMIM c/ Doctor Aiguader, 80 08003 Barcelona e-mail: jalmansa@imim.es [[alternative HTML version deleted]]

...uld I invoke R inside Perl to do the same?? #!/usr/bin/perl open(DAT,"datos.txt"); while (<DAT>) { chomp; push(@datos,$_); } #now I want a histogram of values in @datos Thanks!!

Hi everybody, I've been looking for a function that combines all variables from a dataset because I need to do multivariate regression. If we have linear regression with an expression like f(x) = a0 + sum(ai*xi) what I want to do is something like f(x) = a0 + sum(ai*xi) + sum(sum(bij * xi * xj)) + sum(sum(sum(cijk*xi*xj*xk))) + ... So I need a function that combines all the values from
