Error in vis(bw.glm, B = 150) : FALSE

[jlhanson5]

Hello all,

I was trying to simply run the birth weight example, but get an error.

Here's the code I ran...

library(mplot)
data("birthwt", package = "MASS")
bwt <- with(birthwt, {
  race <- factor(race, labels = c("white", "black", "other"))
  ptd <- factor(ptl > 0)
  ftv <- factor(ftv)
  levels(ftv)[-(1:2)] <- "2+"
  data.frame(low = factor(low), age, lwt, race, smoke = (smoke > 0), ptd, ht = (ht > 0), ui = (ui > 0), ftv)
})
options(contrasts = c("contr.treatment", "contr.poly"))
bw.glm <- glm(low ~ ., family = binomial, data = bwt)
round(summary(bw.glm)$coef, 2)
#
af.bw = af(bw.glm, B = 150, c.max = 20, n.c = 40)
vis.bw = vis(bw.glm, B = 150)

With that last command, I get this error/output:
Error in vis(bw.glm, B = 150) : FALSE

Have other run into this?
