...:
library(lme4)
source("M:/Rcode/lmer2.R") ##(Simply sourcing the modified lmer1 code
below)
set.seed(1)
dat <- data.frame(Y = rnorm(400), X1 = rnorm(400), X2 = rnorm(400),
F1 = as.factor(sample(1:4, 400, replace = T)))
forSm <- Matrix(c(runif(1200)), ncol = 3, sparse = T)
matDim <- dim(forSm)
smoother <- as.factor(sample(1:4, matDim[1], replace = T))
test <- lmer1 (Y ~ X1 + X2 + (1|F1) + (1|smoother), data = dat,
rand_mat = forSm)
the sessionInfo (called after sourcing the code but before the crash)
is:
