Hi, I am looking for a package which allows me to draw arrows (cylinders with cones on them, basically) in 3d images produced with rgl. Is such a thing available? I did notice the 'compositions' package, which contains 'arrow3D'. However, it relies on 'tensorA', which fails to install on my machine with the error message copied below. If anyone can help me fix this problem, that would do the trick too.

Hello, I have been wondering of an efficient way to do this: I have an n x m x p array Z and a p x n matrix Y. I want to multiply each of the n matrices with the corresponding column vector of Y. In other words, I am wanting to matrix multiply: Z[i, ,] %*% Y[, i] which will give me a (two-dimensional) array or matrix of dimension n x p with the i'th row storing the above. Any pointers

...do build their manuals for me on TL2009 on Linux, MacTeX 2009 (a TL2009 derivative) on Mac OS X and current MiKTeX 2.8 on Windows. As far as I can tell, the following CRAN package manuals have been affected: distrMod, RCurl, RGtk2, SparseM, VIM, bit, ggplot2, operators, relations, spam, tensorA (and only distrMod fatally). Given the current pace of change (ca 100 updates/week on 'only' 2000 TL packages), more things may pop out of the woodwork. For the curious and cognescenti: (i) hyperref is having problems with markup in \section titles, which 'methods' and 'd...

Dear all, I need to compute tensor product of B-spline defined over equi-spaced break-points. I wrote my own program (it works in a 2-dimensional setting) library(splines) # set the break-points Knots = seq(-1,1,length=10) # number of splines M = (length(Knots)-4)^2 # short cut to splineDesign function bspline = function(x) splineDesign(Knots,x,outer.ok = T) # bivariate tensor product of
