Hey List, I have a function which has an integral integrate(dnormal, -Inf, towherever) as one of its arguments. Now, R is giving me not just the value for the integral but also adding some text along the lines of "with a maximum error estimate of ...". That's really nice of R but I really just want the number. Does anyone know how to suppress the second part and get the command to just spit out the value of the integral? Thanks, Martin _______________________________________________ gov2001-l mailing list gov2001-l(a)lists.fas.harvard.edu http://lists.fas.harvard.edu/mailman/listinfo/gov2001-l

this isn't quite right. it includes all of elements in the interior of the set, and - for everything we care about - is a closed set. i.e., it includes the boundary. in other words, the convex hull is defined about a set, A, and is the smallest convex set including A. (alternatively, if you deal well thinking in terms of intersections, it is also the intersection of all convex sets that include A.) when in doubt, see aliprantis and border: the convex hull of A is defined as: $\set{x : \exists x_i \in A, \alpha_i \geq 0, \sum_{i=1}^{n} \alpha_i, and x = \sum_{i=1}^{n}\alpha_i x_i}$ john On 4/13/06, ghumphr(a)fas.harvard.edu <ghumphr(a)fas.harvard.edu> wrote: (which of -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ John Gasper, PhD Candidate Dept: Social & Decision Sciences Carnegie Mellon University www.hss.cmu.edu/departments/sds Spring 2006: The Institute for Quantitative Social Science Cambridge, MA 02138 www.iq.harvard.edu _______________________________________________ gov2001-l mailing list gov2001-l(a)lists.fas.harvard.edu http://lists.fas.harvard.edu/mailman/listinfo/gov2001-l
