In addition, you can simplify the data manipulation:
wide <- matrix(c(20, 26, 16, 29, 22, NA, 12, 24, 17, 21, NA, 17), nrow = 6,
dimnames = list(subject = paste("s", 1:6, sep = ""), myfactor =
c("f1", "f2")))
long <- as.data.frame.table(wide, responseName = "dv")
am2 <- lmer(dv ~ myfactor + (1|subject), data = long)
