Re: [R] QP.solve, QPmat, constraint matrix, and positive definite

i found the posdefify, nearcor, and nearPD functions, but can't get things to work. when i tried nearPd, it gave me an dpoMatrix, but i don't know if it would have worked because it said: 31 x 31 Matrix of class dpoMatrix right between $mat and the actual matrix and i don't know how to cut that

[R] QP.solve, QPmat, constraint matrix, and positive definite

hello all, i'm trying to use QPmat, from the popbio package. it appears to be based on solve.QP and is intended for making a population projection matrix. QPmat asks for: nout, A time series of population vectors and C, C constraint matrix, (with two more vectors, b and nonzero). i believe the

[R] error message translation

sorry if my first msg was posted twice. this email system at school sucks. i've looked in the Admin and Main manual and the Intro manual for something that tells me what error messages mean, but haven't found anything. where can i find the meanings of the error messages?

Re: [R] installing and using a package

-Original Message- You need to read the An Introduction to R manual which was probably installed when you installed R on your un-named OS (Windows, I take it). yes, i did find what i needed there. thanks you. john __ R-help@r-project.org

Re: [R] error message translation

Do you mean expansions on the terse messages, or translations from another language? There aren't really any expansions available: the messages are supposed to be clear in themselves. If you really want to know why you got one you might be able to look it up in the source code, but
