Dear R-users,
I was wondering for the following:
Let 'x' be a matrix and 'ind' and indicator matrix,
i.e.,
x <- array(1:20, dim = c(4, 5))
ind <- array(c(1:3, 3:1), dim = c(3, 2))
I'd like to get (as a vector) the elements of 'x'
which are not indexed by 'ind'. Since negative indices
are not al
Dear R users,
I've been struggling some days with the following
problem: I'm interesting in producing the following
plot
x <- seq(0.01, 10, length = 20)
plot(c(0, 10), c(-20, 20), type = "n", xlab = "x",
ylab = expression(2 * alpha * log(x)))
pch. <- rep(NA, length(x))
for(i in 1:4){
Dear R users,
I've been trying to build R from sources (in Windows) using Dr. Goto's BLAS,
unsuccessfully! I've followed the instructions in Section 3.1.2-3.1.3 of "R
Installation and Administration" manual (but maybe I did something wrong), but I
keep receiving the following error:

Dear R users,
I've been struggling with the following problem: I want to extract the Wald
p-value
from an lmer() fit, i.e., consider
library(lme4)
n <- 120
x1 <- runif(n, -4, 4)
x2 <- sample(0:1, n, TRUE)
z <- rnorm(n)
id <- 1:n
N <- sample(20:200, n, TRUE)
y <- rbinom(n, N, plogis(0.1 + 0.2 * x
