[R] Equal length axis

Dear useRs, I am having difficulty to plot graphics with mfrow command, where both axis are equal length. Below is sample code, which plots rectangles instead of squares: par (mfrow=c(3,3)) qqnorm(a) qqnorm(b) ... .. Thanks in advance for any pointers or notes.

[R] Equal number of cuts in a contourplot with trellis

Dear R-helpers, I need some help to produce a set of contour plots that I am trying to make in order to compare surfaces between the levels of a factor. For example: library(lattice) g <- expand.grid(x = 60:100, y = 1:25, ti = c("a","b","c")) g$z <-with(g, (-1e-4*x-1e-3*y-1e-5*x*y)*(ti

[R] equal

using the same a and b, why solve(a,b) get a 1 by n matrix while solve(a)%*%b get a n by 1 matrix. I thought they should be equal to each other... __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the po
