Hi! I have two one dimensional integrals. One starts from a (+,-)real number and goes to positive infinity, the other starts from negative infinity to a (+,-) real number. My questions are: 1) Can I use the add on package "inegrate" which seems to be designed for integrals limited by real numbers? 2) If not, is there any other package that I can use? Thank you for your time, Sencer -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)

Not really. If you know that the contribution to the integral is negligible outside a certain region then you can trim that region off (eg some probability densities), but the code is designed for finite boxes -thomas Thomas Lumley Assistant Professor, Biostatistics University of Washington, Seattle -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
